I am Testing the Workflow Action Pack. I have created an Workflow with Send Email with Attachment. Sometimes the workflow couplets successfully but sometimes it throws a Error Message like Exception: There was an error processing the request.
In ULS Logs I can compare the successful runs with the not successful and I see some Issues related to Authentication.
Is there something in the Workflows to turn on Trace Logging to get some more Information about what went wrong? We have a Two Frontend, two Cache, Two Application with Search topologie
