[BUG] bearerAuth security scheme not resulting in access_token being used to create Authorization header.

Description

Having generated a Python client from an OpenAPI spec including the following securityscheme:

  securitySchemes:
    bearerAuth:
      type: http
      scheme: bearer
      bearerFormat: JWT

It is not possible to use the access_token configuration parameter in the resulting client. Passing it to openapi_client.Configuration on instantiation, or adding it to the instantiated object, does not result in the Authorization header being passed in requests.

openapi-generator version

7.3.0

OpenAPI declaration file content or url

  securitySchemes:
    bearerAuth:
      type: http
      scheme: bearer
      bearerFormat: JWT

Generation Details

docker run --rm \
  -v ${PWD}:/local openapitools/openapi-generator-cli generate \
  -i /local/myspecification.yaml \
  -g python \
  -o /local/client

Steps to reproduce

"""Testing the OpenAPI client."""

import openapi_client
from openapi_client.rest import ApiException
from pprint import pprint


configuration = openapi_client.Configuration(
    host="https://myapi.com/v2.5.6"
    access_token="my_token"
)


configuration.debug = True

configuration.access_token = "my_token"


with openapi_client.ApiClient(
    configuration,
) as api_client:
    api_instance = openapi_client.DefaultApi(api_client)

    try:
        api_response = api_instance.get_building_by_id(20)
        pprint(api_response)
    except ApiException as e:
        print("Exception when calling DefaultApi->get_building_by_id: %s\n" % e)

Debug output:

send: b'GET /v2.5.6/buildings/20 HTTP/1.1\r\nHost: myapi.com\r\nAccept-Encoding: identity\r\nAccept: application/json\r\nUser-Agent: OpenAPI-Generator/1.0.0/python\r\n\r\n'

Seems related:

But stated fix of setting saccess_token after instantiation of the configuration class doesn't appear to work. And the issue says it was fixed in v6. Indeed, configuration.py in the generated code does seem to include the requisite fixes:

self.access_token = access_token
        """Access token
        """

...

    def auth_settings(self):
        """Gets Auth Settings dict for api client.

        :return: The Auth Settings information dict.
        """
        auth = {}
        if self.access_token is not None:
            auth['bearerAuth'] = {
                'type': 'bearer',
                'in': 'header',
                'format': 'JWT',
                'key': 'Authorization',
                'value': 'Bearer ' + self.access_token
            }
        return auth

Suggest a fix

I can't seem to trace down the code which is ignoring the auth_settings. There appears to be no other code that references auth['bearerAuth'].

Start with the generated Python client's configuration.py, especially auth_settings, and trace how ApiClient uses those settings when building requests. Use the supplied bearerAuth specification and reproduction to check why the Authorization header is absent, then verify that requests include the Bearer token when access_token is configured.
