The migration script changes the column 'func' from text to a bytea column, while keeping content in the correct format.
It fails because the column is *already* a bytea column. I don't how it could happen because the migration script is not supposed to run twice. The solution for you is to comment the content of the file connector/migrations/2.2.0/pre-migration.py before the upgrade.
