makemigrations error

[Taurdil]

Hello. I'm trying to create a plugin according to the instructions: https://netbox.readthedocs.io/en/stable/plugins/development/
But at the stage "Database Models" I get an error:

./manage.py makemigrations netbox_animal_sounds --traceback

Please tell me where I could have made a mistake.

will take you to:

See also https://netbox.readthedocs.io/en/stable/configuration/optional-settings/#developer
However it would be a good idea if this were linked from the plugin developer page.
