I am experiencing this same issue. What version of scipy did you install? And is there any other fix than this?

Submission process for Certified Connectors

BreannaNery — Sat, 05 Sep 2026 00:44:40 GMT

I'm one of the owners of a certified connector (Autodesk Forma). Historically, we've been instructed to submit updates for our certified connector over email.

We submitted an update for our certified connector in July 2026 and have yet to receive a response from our usual contacts. Has any changes been made to the certified connector submission process?

Re: Fabric keeps deleting files!!

We had some semantic models in a workspace and were trying to put in them in separate workspaces for security reasons. New workspaces were created in Fabric and the semantic models were deployed using the Tabular editor. I also started working on a Power BI report directly in the workspace. I was doing this for about 3 or 4 days, I did no other operations. I also did the same thing for a different workspace. One day I loaded up fabric and both these workspaces were completely empty. I lost a good deal of work in one of them, the other one I luckily had setup github so I was able to recover them. Also please note that it also deleted all the folders I had created, so it was not a "woops" moment where I accidentally deleted a semantic model.

This is usually a Git sync-direction issue rather than random deletion — "Update from Git" reconciles the workspace to match the connected branch, removing anything not present there.

Hi alloowishus,

Thanks for the clarification and for providing the additional context.

Based on your description, the workspaces were not connected to Git when the items were deleted, so the Git branch-out or branch-switching behavior discussed above would not apply to this scenario.

Since you've observed the same behavior across multiple newly created workspaces, including for your colleague, it would be helpful to gather some additional details to investigate the behavior further. In particular, the types of items affected, the approximate time when they disappeared, and any workspace or deployment operations performed before the items were deleted could help narrow down what happened.

If you can reproduce the behavior, sharing the steps leading up to the deletion and any relevant error messages or timestamps would also be useful for further investigation.

Thank you.

Re: exportToFile: reportLevelFilters AND a single-select slicer's default value → empty page

LumericVisuals — Thu, 03 Sep 2026 15:54:43 GMT

I don't have documentation-level confirmation of the exact precedence, but from how exportToFile behaves in practice, defaultBookmark sets the report's starting state, and reportLevelFilters layer on top of that.

So a bookmark that sets the slicer's selection to the same value as your export filter should remove the conflict, since bookmarks do capture single-select slicer state — they just can't clear it to nothing, same limit as report.reset().

That's lighter than disabling single-selection or duplicating the page, but it's still a one-time report-side edit, not a pure payload-only fix.

Worth testing since it's non-destructive: add the bookmark, point defaultBookmark at it, and see if the intersection resolves the way you'd expect.

Re: PBIP Report page fails to render after adding custom visual via Power BI authoring API

LumericVisuals — Thu, 03 Sep 2026 16:06:57 GMT

This isn't a page.json/visual.json problem on its own — registering a custom visual by type name isn't enough for the renderer to know how to load it.

When Desktop adds a custom visual through its own UI, it also writes a resource/import registration that tells the renderer where that visual's actual package lives; a built-in visual doesn't need this because its type is already known to the local registry.

Since your script only writes the visualContainers entry and not the matching resource-package/import declaration, the registry lookup for that type comes back completely undefined instead of "known but missing," and the page bails instead of degrading gracefully.

Fastest way to find the exact shape you're missing: add one custom visual by hand in Desktop, save as PBIP, and diff the report-level files before/after — there should be a new entry outside page.json/visual.json that your script isn't generating yet.

Hi KumbharM,
Thank you for the detailed information. Please verify that the MCP-generated PBIR follows the documented PBIR structure, including definition/report.json with the custom visual’s exact publicCustomVisuals unique name matching visual.visualType. Also verify that the visual is located under the documented definition/pages/<page>/visuals/<visual>/visual.json structure and that the applicable JSON schemas are valid. These checks will help confirm that the custom visual is correctly represented in the PBIR definition.

Re: exportToFile: reportLevelFilters AND a single-select slicer's default value → empty page

v-achippa — Thu, 03 Sep 2026 09:58:54 GMT

Hi Ceo_psh,

Yes, your understanding is correct. The bookmark can preserve a slicer selection, but it cannot provide a ‘no selection’ state when require single selection is enabled.

Since the slicer value is dynamic for each export, there is no API side option in exportToFile to clear or ignore that existing slicer selection. So the recommended approach is to use a separate export only page without the single select slicer and apply reportLevelFilters to that page.

Thanks and regards,
Anjan Kumar Chippa

PBIP Report page fails to render after adding custom visual via Power BI authoring API

KumbharM — Thu, 03 Sep 2026 07:25:43 GMT

Environment:

Power BI Desktop: August 2026 (version 2.157.xxx, PBIR format with PBI_enhancedReportFormat enabled)

Format: PBIP (Power BI Project) — PBIR mode

Authoring method: Fabric MCP / Power BI Authoring Skill (programmatic JSON file generation)

OS: Windows 10/11

What I am doing

I am using the Microsoft Fabric MCP server and Power BI authoring skills to programmatically scaffold PBIP projects and add visuals by writing visual JSON files directly under:

MyReport.Report/

└── definition/

└── pages/

└── {pageId}/

├── page.json

└── visuals/

└── {visualId}/

└── visual.json

I add standard built-in visuals (barChart, donutChart, treemap, columnChart, tableEx, card) using schema 2.12.0 and register each visual ID in the visualContainers array in page.json.

What I expect

Power BI Desktop opens the .pbip file and renders all visuals on the page correctly — the same behaviour as when visuals are added interactively through the UI.

What actually happens

After adding custom visuals (e.g., from AppSource or .pbiviz files) programmatically and registering them in page.json, the entire report page fails to render. The error shown is:

"An error occurred while rendering the report"

Inspecting the browser console (via PBI Desktop's developer tools) shows:

Cannot read properties of undefined (reading 'visualContainers')

Even though visualContainers is correctly populated in page.json, the page renderer crashes when encountering a custom visual whose type string (e.g., Gantt1448688115699) is not recognized by the locally available visual registry at render time.

The crash is not isolated to the custom visual itself — it takes down the entire page, preventing all other standard visuals from rendering too.

Steps to reproduce

Create a PBIP project with PBIR format (modern definition/ structure).

Add 5 standard visuals (card, barChart, donutChart, treemap, tableEx) via JSON files — all render fine.

Add 1 custom visual (AppSource, e.g., Gantt or Chiclet Slicer) via a JSON file with "visualType": "<customVisualTypeName>".

Open the .pbip in Power BI Desktop.

Result: Entire page is blank. The JavaScript error Cannot read properties of undefined (reading 'visualContainers') is thrown.

Expected: Custom visual shows a placeholder/error tile; remaining 5 standard visuals render normally.

Re: Fabric keeps deleting files!!

alloowishus — Wed, 02 Sep 2026 13:36:01 GMT

This isn't it. I had setup a new workspace and deployed a semantic model there from Tabular editor and also setup up some folders. I found these items completely deleted and I had NOT setup github (everything was lost). This also happened on another workspace, but I did have github setup so I was able to recover. This also happens to my colleague when setting up new workspaces. It's very frustrating.

Re: exportToFile: reportLevelFilters AND a single-select slicer's default value → empty page

Ceo_psh — Wed, 02 Sep 2026 13:29:17 GMT

Thanks v-achippa — that matches what I was seeing.

One follow-up so I can close this off: can you confirm that `defaultBookmark` /`pages[].bookmark` in the `exportToFile` payload cannot override a single-select slicer either?

My understanding is that single selection is a formatting property of the visual, so a bookmark can capture a different selected value but can never produce a "nothing selected" state for such a slicer — meaning there is no API-side workaround at all, and the export-only page is the only viable option when the filter value is dynamic per export.

(Saving the slicer with the required value before exporting isn't an option in my case — the value differs for every export request, so it would mean writing to a production report on each run.)

Re: Fabric keeps deleting files!!

Hi alloowishus,
Thanks for reaching out to the Microsoft Fabric Community forum.

If the files are disappearing during Git branch-out or branch-switching operations, this behavior is documented by Microsoft.

When branching out, items that aren't saved to Git can get lost, and Microsoft recommends committing any items you want to keep before branching out. When switching branches, the workspace is synchronized with the new branch. If an item exists in the old branch but not in the new branch, that item is deleted from the workspace.

If the files are being deleted outside of these Git operations, additional details about the operation performed before the files disappeared would be helpful in determining the cause.

For more details, please refer to the below Official Microsoft Documentation:
Overview of Fabric Git integration - Microsoft Fabric | Microsoft Learn
Development process using Branch-Out experience - Microsoft Fabric | Microsoft Learn

I hope this helps. Please feel free to reach out if you have any further questions.
Thank you.

Re: exportToFile: reportLevelFilters AND a single-select slicer's default value → empty page

v-achippa — Wed, 02 Sep 2026 12:11:25 GMT

Hi Ceo_psh,

Thank you for reaching out to Microsoft Fabric Community.

Here looks like the issue is because of the existing single select slicer value being applied together with the reportLevelFilters value. Like for example, if the slicer is set to B and the export filter specifies A, both filters are applied, resulting in no matching data and therefore a blank page.

Create an export only report page without that slicer and apply reportLevelFilters to it. Alternatively, save the slicer with the required value before exporting.

Thanks and regards,

exportToFile: reportLevelFilters AND a single-select slicer's default value → empty page

Ceo_psh — Wed, 02 Sep 2026 10:44:57 GMT

**Setup:** Power BI Service, workspace on Fabric capacity (not PPU). Export via `exportToFile` (PPTX) from Power Automate. Server-side only — no JavaScript embedding, so `bookmarksManager.capture()` and `report.reset()` are not available to me. Report-level filters work correctly on pages without slicers on the filtered column. **Problem:** on a page with a slicer that has **Require single selection** enabled, the slicer keeps its saved default value, and my filter is applied on top of it. Since both conditions target the same column and the values differ, the intersection is empty and the page exports blank.

"powerBIReportConfiguration": {
"pages": [ { "pageName": "ReportSectionXXXX" } ],
"reportLevelFilters": [
{ "filter": "MyTable/MyColumn eq 'A'" }
]
}

Slicer default is `'B'`. Result: empty page. The only value that exports correctly is `'B'` —the one the slicer already holds. I understand *why* this happens: a report-level filter narrows the values available to a slicer but never changes the slicer's selection, and preexisting filters combine with the new filter using AND. With single selection enabled, the slicer can never be cleared, so the conflict is unavoidable from the report's default state.

**What I'm asking:** is there anything on the API side that resolves this without editing the report?

Can `defaultBookmark` or `pages[].bookmark` override the slicer's selection during export, or is single selection a formatting property of the visual that a bookmark cannot affect?

2. Is the precedence between a bookmark and `reportLevelFilters` documented anywhere? The only statement I've found is that export filters are applied *in addition to* the current report state, which reads as AND.

3. Is there any payload option that exports a page as if the slicer weren't there — a server-side equivalent of `report.reset()`?

4. Would moving the field into the "Filters on this report" pane change how the export resolves the conflict?

If the answer is "no API-side option exists", a confirmation I can point to would already help — the remaining path is a report-side change (disabling single selection, or an export-only copy of ,the page without the slicer)

We also use an on-premises data gateway. The gateway data source connection is updated dynamically using the Power BI Update Datasource REST API. Based on the server and database values, we update the corresponding database parameter in the Power BI report.
