Please ensure all legacy provider contact data has been migrated to contact objects before proceeding. Or, set the NETBOX_DELETE_LEGACY_DATA environment variable to bypass this safeguard and delete all legacy provider contact data.

Expected Behavior

Running Version 3.4.2

Same here, I had to do:

sudo PYTHON=/usr/bin/python3.9 NETBOX_DELETE_LEGACY_DATA=1 ./upgrade.sh

Remembering that this will delete the contact data from the provider, so first you should create a new Contact object and populate it with the necessary data.
