Notebook execution failed at Notebook service with http status code - '200'

Hi DTTeam4 
Thanks for using Fabric Community.
Can you please provide the code which you are running in the Notebook? This helps me in understanding the issue better.
The error refers to a Managed Workload Center (MWC) token, which is used for authorization when accessing resources like Hive within a secured cluster.

Possible Causes:

1. Missing MWC Token Configuration: Your notebook might not be configured to retrieve the MWC token needed for Hive access.
2. Incorrect MWC Token Permissions: Even if configured, the MWC token might lack the necessary permissions to access Hive resources.

Troubleshooting Steps:

1. Check Notebook Configuration: Review your notebook code for any sections related to MWC token configuration. Ensure it's set up correctly to retrieve the token before accessing Hive.
2. Verify MWC Token Permissions: Investigate the permissions associated with the MWC token being used. It needs to have read/write access to the Hive Metastore and any relevant databases/tables you're trying to access.
