Hi @yogendra-yogi

Can you please go to the flow directly and see what happened there.

Also can you share, is this a Topic, or a Tool that you call Dynamically via AI?

BTW, just to verify, you said this is a Typical error? so you get this a lot?

Lastly, i noticed the name has fabric in it, is this a Fabric mirrored instance or the actual SQL Server?
