Hi Kaniz

Thanks for taking your time to reply. 

Widgets: widgets is not a part of the problem as we have tested hardcoded values (strings and dates) that replace the need for widgets. Still no luck.

Cluster: Regarding your tip on cluster configurations, there is very limited configurations on a serverless cluster in comparison to a notebook cluster, so Im not sure about how we can align the clusters at all. 

Dependencies/Libraries: We use only built-in libraries and dependencies in the notebook cluster and again, since the serverless cluster have limited configurations, this does not seem to be the issue.

Clearing output: We have tried that.

Where can I get in touch with a databricks expert?
