Debugging dataflows Unexpected Error with Session ID

I am pretty new to dataflows, so I apologize for the simple question.   Often when creating a dataflow, I will receive a popup message saying "Unexpected error: We encountered an unexpected error."  ...

Hi nqzhhzmn 


Could you confirm with your network admin that they are not making the time to re-authenticate to short?

    I am the network admin.  We are a very small company, so I do all IT related stuff.

        I am an admin in the workspace, so that isn't the problem.  The solution is just to start over and re-author the dataflow, then it works.  Somehow, the logic of the dataflow is just getting too much for Power Query to handle, and there is some mistake in the logic, so it just gives up.  

        I just wish I could fire up gdb, attach to the core file and see where it bombed.  A reliable way to find the issue is definitely missing.
