Power Bi Report Server May 2025 Errors
I upgraded my Windows Server 2019 from Power BI Report Server (May 2024) to Power BI Report Server (May 2025) and am now seeing the following errors in the browser's console: https://dev.my-site...
Additional info: these errors only appear in the console when opening a Power BI report saved using Power BI Desktop (May 2025) for Report Server.
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
