The 401 Unauthorized error you're encountering is likely due to a limitation in the Microsoft Fabric REST API. Specifically, not all Fabric APIs, including those related to OneLake Shortcuts, currently support Service Principal authentication, even if the Service Principal is an admin of the workspace.
Workaround for Unsupported APIs:
- Use user delegation authentication. Authenticate the API request using a user account with sufficient permissions (e.g., owner or admin)
