See kubernetes-client/python#1032 (comment) for full details.

Multiple response content types are deserializable in the python-experimental generator
One can see them here: https://github.com/OpenAPITools/openapi-generator/blob/master/samples/openapi3/client/petstore/python-experimental/petstore_api/api_client.py#L936
And they include:

• 'application/octet-stream'
• json
• 'multipart/form-data'
