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

    Thanks everyone we have managed to resolve this be removing the ULR and certifcate bindings again and re-apply them and that seems to have solved it.

    I should say that the files we are trying to publish are tiny - just a couple of test files with no to little data in them.

    Hi Denise_mac ,
    Its been a while i had the pleasure to implement Report Server on enterprise servers, i did get all kinds of problems along the way.


    The browser console only shows the generic 422. The more useful error should be in the Report Server logs around the same time, especially entries around:

       - /api/v2.0/catalogitems
       - /api/v2.0/powerbireports
       - Model.Upload
     
    One thing that is always overlooked is permissions, you are probably using service account to run the report instance, and that service account needs its own rights. While upgrading can reset all the permissions to default, so check and compare permission between the working version you have and the one having problems.

    Also list down every functionality that is not working, not just upload, then maybe we can draw conclusion and pinpoint the root of cause.

    Please check similiar thread that is solved too:

    When you get this 422 Unprocessable Entity error, your report server rejects your upload of PBIXs because there’s an issue on the server side.

    Make sure that the Power BI Desktop for Report Server has a matching version to the one on the server. Check the logs of the report server for more details about what exception happens. Try uploading a blank PBIX file. If all the pbix files are failing, try repairing/reinstalling the report server. Validate that the ReportServer database was upgraded correctly.
