Command line used for generation

Steps to reproduce

In controllers/security_controller_.py

return {'scopes': ['read:pets', 'write:pets'], 'uid': 'user_id'}

Suggest a fix

There should not be a default scopes, uid value even if it's not properly configured
(I couldn't see where to define uid in the openapi spec)

Start by regenerating the Python Flask server with the provided OpenAPI declaration and npx openapi-generator generate -i openapi.yaml -g python-flask. Inspect controllers/security_controller_.py, focusing on the generated OAuth security handling. Done means the generated code no longer emits the hard-coded read:pets, write:pets, or user_id defaults when the specification does not define them.
