Failing to infer content when application/problem+json is present in another response code

[carloscbl]

Description

When having 2 reponse types one is problem+json is unable to infer response

Expected behaviour

Should be able to infer that is a dictionary with no header and asume is json response or just check 200 response is always application/json

Actual behaviour

if another response like 401 is present with a different content type like application/problem+json should still be able to infer is a json

Steps to reproduce

as API

  /potato/advanced-configuration:
    get:
      summary: xxx
      responses:
        '200':
          description: OK
          content:
            application/json:
              schema:
                $ref: '#/components/schemas/xxx'
        '401':
          description: Returned if the calling user does not have permission to perform the operation.
          content:
            application/problem+json:
              schema:
                $ref: ../common/models/error.v1.yaml
      operationId: configuration.get_configuration

def get_configuration():
    try:
        response = cb_conf.read_conf() or {}
        status_code = 200

    except Exception as ex:
        logging.error(f"Error getting configuration: {ex}")
        response, status_code = unexpected_exception(ex), 400
    print(response, status_code)
    return response, status_code

Additional info:

Output of the commands:

• python --version 3.11
• pip show connexion | grep "^Version\:" 3.1

Is #2054 related to this?

In that issue I document how I cannot seen to return an octet-stream without getting this error unless I disable response validation.

Would you please update this issue with a small self-contained code + spec example that exhibits the failure?
