Public bug reported:

Hi,

Due to some completely different issue, we had ports with port_tags None created in production. Under normal circumstances, it would take some error to the log and go further.
But only because there is a "new_vlan_tags must be string" in that log, it threw out typeError and dropped the execution of code and the migration ended by code 500.

And without a message from the log, which is extremely bad.
It was able to go through the repair of the logo
