'VehicleGuidModel' object has no attribute 'model_dump_json'

[AndreaCovelli]

When running simple_client_example.py and decommenting the line
pp.pprint(car._dump_all()) # pylint: disable=W0212

the python script returns an error saying:

AttributeError: 'VehicleGuidModel' object has no attribute 'model_dump_json'

Investigating the code, I found that the attribute isn't specified inside the code, maybe because it should be retrieved by the api for my specific car model. For info, the car is a toyota yaris cross. Thanks for reading.
