The following error message is output when executing an action that requires approval for a form in the Flow Designer.
How to deal with it?

Hi

The PlanRecursionException is thrown when there is a recursive call to the flow itself from within the flow.

The recursion might be in any of the steps, including custom scripts or even in the Trigger's "Run Trigger" which might be set to 'For each unique change' (and there is an update to the trigger record in any of the flow steps).

Make sure that there are no recursions in the flow.

I am getting same error for OOB flow, can you let me know what fixes you have applied. 

Thanks,
