Hi alloowishus,

Thanks for providing the additional details and for clarifying the sequence of events.

Based on your description, the workspaces were not connected to Git, and you did not perform any other workspace operations during the 3 to 4 day period. Therefore, the Git-related deletion scenarios discussed earlier do not appear to apply to this situation.

The fact that multiple workspaces were affected and that the semantic models, reports, and folders were all missing is important context. To help narrow down what may have occurred, could you provide the approximate date and time when you last confirmed that the items were present and when you first noticed that the workspaces were empty?

If available, any relevant activity or audit information from that timeframe would also be helpful. If the issue occurs again, providing the steps leading up to the behavior, along with the affected workspace and item types and approximate timestamps, would help with further investigation.

Thank you for the additional information.

Re: Submission process for Certified Connectors

v-abhinavmu — Mon, 07 Sep 2026 04:42:59 GMT

Hi BreannaNery,
Thank you for bringing this up.

According to the current Microsoft documentation, updates to an existing certified connector follow the certification process. For verified publishers, connector updates are submitted through Partner Center.

For an existing certified connector, Microsoft recommends reopening the existing offer in Partner Center and updating the relevant section under Product Overview. A new offer should not be created for an existing connector update. Once the update is submitted, Microsoft reviews the updated connector and, if it passes certification, provides a preview environment for testing. After testing is completed, the publisher can confirm Go live in Partner Center, after which Microsoft proceeds with deployment.

Since your update was submitted in July and you have not yet received a response, I would recommend checking with your usual Microsoft contact regarding the status of the submission and whether any further action is required.

For more details, please refer to the below Official Microsoft Documentation:
Update your certified connector | Microsoft Learn
Verified publisher certification process | Microsoft Learn

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

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.
