SOLVED - Cannot activate any changes

Troubleshooting
1

Continuing the discussion from Activate pending changes : python error:

Even after clearing all pending and adding a simple change (ip address of an AP) I get the same error: argument of type 'NoneType' is not iterable
I’m going to disable piggyback. Can someone let me know:

  • Is this my error?
  • Is this a bug in piggyback?

Either way, I cannot apply any changes.

:smiley: Solved! Thanks to some really good detective work. Didn’t even need to restart, it just worked.
