Power Bi Report Server May 2025 Errors
Hello KenCBowman,
Thank you for reaching out to the Microsoft Fabric Community Forum. The errors are likely due to incomplete deployment of static resources or missing Copilot-related services introduced in the May 2025 release.
Please consider the below points:
- Re-run the May 2025 installer and choose repair to ensure all files are correctly deployed. Upgrade Power BI Report Server
- Check that styleLibrary.js exists in the libs/scripts folder and is served with the correct MIME type (application/javascript). Adding Static Content MIME Mappings <mimeMap> | Microsoft Learn
- The May 2025 release includes Copilot features. Make sure all required services and dependencies are properly configured. Power BI Report Server May 2025 Release Notes
If you have any further questions, please don't hesitate to contact us through the community. We are happy to assist you.

As I mentioned, I have already tried reinstalling and it did not fix the errors. Despite these errors, all of my reports work fine, but I'd like to resolve these errors becasue something is clearly wrong with the install.
Where do I find styleLibrary.js in the folder structure on the harddrive (did this file exist in the May 2024 release)? I assume the mime issue is related to the file not existing.
I didn not see any special references in your link to services and dependencies required by Copilot. What are those?
Thanks,
Ken
