PowerBI Workspace Not Found" Issue

Hi mahendra9490​ ,

This issue typically means the Service Principal can authenticate, but doesn’t have effective access to the workspace. Please confirm that Service principals can call Fabric public APIs is enabled in the Fabric Admin Portal, and that the Service Principal has been explicitly added to the target workspace as Member or Admin.

If you’re using Deployment Pipelines, the Service Principal also needs Pipeline Admin permissions in addition to the workspace permissions.
