# Dry run issues

#### Problem:
sqlalchemy.exc.InvalidRequestError: When initializing mapper mapped class ConfiguredSync->configured_syncs, expression 'ConfiguredSync.reverse_connector_id == ReverseConnector.id' failed to locate a name ("name 'ReverseConnector' is not defined"). If this is a class name, consider adding this relationship() to the <class 'datachannel_models.configured_sync.ConfiguredSync'> class after both dependent classes have been defined.

#### Solution:
Add **datachannel_models.reverse_connector.ReverseConnector** import in the script itself
