Comment 1 for bug 1977865

While reproducing the steps I found this in the debug-log

unit-metacontroller-operator-0: 11:40:12 ERROR unit.metacontroller-operator/0.juju-log Uncaught exception while in charm code:
Traceback (most recent call last):

Can you confirm this is not an issue related to the charm itself?
