Hi @sunnypol, start by checking the Data Access Configuration properties in the Workspace Settings to ensure that the necessary secrets exist and that the cluster's owner has the proper read permissions. Verify that the user has read access to any secret scopes configured, and double-check the Spark configurations for accuracy. Also, ensure that resource quotas, particularly if you're using Azure, haven't been exceeded.
Let me know if you need more detailed guidance on any of these steps!
