Input Slicer Filtering Rule Stops Working After Publishing to Report Server
Hi everyone, I have a question regarding the "Input slicer" visual in Power BI. I created an input slicer in Power BI Desktop and set the filtering rule to "Does not contain any". It worked perfectly in Desktop during my local tests, filtering data as expected. However, after publishing this report to our on-premises Power BI Report Server, the input slicer's behavior seems to have changed: The operator dropdown button is missing: The dropdown button that allows me to switch between operators (e.g., "contains", "does not contain") in Desktop is no longer visible on the server. Filtering logic appears different: When I enter a value, it seems to apply an exact match logic instead. Only when I type the complete and exact value can it filter the data. The "does not contain any" rule I originally set no longer seems to work. Has anyone else encountered this issue? What could be the possible causes? Is this due to limited support for the input slicer visual in certain Report Server versions, or could it be that I missed some important step before publishing? Just to add more details to this issue: I recently upgraded our Power BI Report Server from the September 2025 version to the May 2026 version (version 15.0.1121.120) I'd really appreciate any insights or suggestions! Thanks in advance.
Unable to upload PBIX files
Hi there, We are getting the following error when trying to upload reports to our report server. It was at the January 2026 version and we tried to update it to May 2026 version to see if that resolved the issue, but we get the same message with the May version as well. We had previously been able to create reports in the January 2026 desktop version and upload them to the server okay and have also tried to create reports in May 2026 desktop version and upload but nothing seems to work. Our live server (January 2026 still) still works okay. We can upload PDFs or text files to the server okay. It just seems to throw the error when you try to upload a PBIX file. If i check the console when I try to upload any reports we get the following error: and have checked the server logs and get the follwoing polyfills-KEOJFKRO.js:1 POST https://XXXXXXXXX/Reports/api/v2.0/catalogitems 422 (Unprocessable Entity) (server address removed) We have tried googling those to see if there is a fix or known issue for that but can't really find any information on those 2 errors. We have checked the certificates on the server and they seem to be okay and have the correct binding. We are at a bit of a loss on how to resolve this - does anyone have any ideas? Thanks Denise
PowerBI January 2026 Update - On-Premise Reporting Server
I have noticed a bug with RLS Pbix files, where the normal behavior in our May 2025 environment was giving greyed out visual and not showing the data, after upgrading to January 2026 on test environmnet. the behavior has changed and it automatically refreshes indefinitely until an RLS is set. the page keeps reloading with error 401 unauthorized.
