I am getting the error Debug session is already terminated. in Data flows. What can I do?

Question

This error is before I can even get to building a pipeline. In short here are the steps to reproduce the error I am having:

1. Create new dataflow in Synapse Workspace.
2. Click on the toggle to activate Data flow Debug.
3. Error message is dsiplayed saying Debug session is already terminated

In short I cannot activate data flow debug and the only error message I get is Debug session is already terminated.

Hello @Rickus du Plooy Sorry to see the error causing the inconvenience!

Which region was it causing the issue? and how long was the Debug time selected?

Did you try creating the Synapse in other region?

We are here to help you on this issue!

Here are some possible solutions that you can try:

Check if there are any active debug sessions: You can check if there are any active debug sessions in your Synapse workspace. If there are any active debug sessions, you can terminate them and try again.

Check if the integration runtime is running: You need to have an integration runtime running to debug data flows in Synapse. You can check if the integration runtime is running and try again.

Check if the data flow is valid: You can check if the data flow is valid by clicking on the "Validate" button in the data flow designer. If there are any errors or warnings, you need to fix them before you can activate the debug session.

Check if the data flow is too complex: If the data flow is too complex, it may cause issues with the debug session. You can try simplifying the data flow by removing unnecessary transformations or splitting the data flow into smaller parts.

Check if there are any network issues: You can check if there are any network issues that may be causing the error. You can try restarting your network connection or using a different network to see if it resolves the issue.
