Hit unexpected exception, please retry. If the problem persists, please contact Azure Support

Hi @jg,

Thanks for contacting to Microsoft QA.

Based on the details you've shared, it appears you're encountering a system-level issue in Azure Synapse Studio where your dataflows are triggering an unexpected exception, and you're unable to initiate a debug cluster. The error code and message suggest that this may be related to a system error within the platform. We're here to help you resolve this as quickly as possible.

To help us move forward effectively, could you please assist by answering the following questions? This will enable us to narrow down the issue and provide more targeted support -

1. Do you still experiencing the above stated issue?
2. Could you please share any recent changes made to the dataflows or the environment that might have coincided with the onset of the issue?
3. Are you able to access any logs that might give more context to the error?
4. What specific actions are you taking when the error occurs, and what Azure region are you working in?

Your patience and understanding are truly appreciated.

Thanks,
Vrishabh

I'm getting a similar problem in UK South with one Synapse instance but not another. Error doesn't seem to show up in the workspace logs.
'Internal server error executing the request.' when trying to start debug cluster or run a pipeline with a dataflow inside it.

thanks, Mark
