Facing the same issue while calling https://api.fabric.microsoft.com/v1/workspaces. As it is not referring to a particular workspace, can it also be due to permissions given in workspace? { "requestId": "94f4be0a-d3e9-48b4-bcfa-836ab373bc1b", "errorCode": "Unauthorized", "message": "The caller is not authenticated to access this resource" }. [![enter image description here][1]][1] How was this resolved?
