Has anyone ever run into an issue where they get the error `Nonetype object has no attribute 'to_sql` but *only* in production? I've spot checked and my load statement is constructed identically, registration is fine, etc. Local runs go fine as well.

I think this means your upstream task is returning `None`. I think it might help you to log some output inside the task before it’s returned to get an idea

This is a part of a case statement, so the upstream task is the condition check. I put in some print statements and its definitely returning things

Could you show the Flow definition (just the Flow block)?
