Basic authentication with Python API does not work in main Airflow

Apache Airflow version

main (development)

If "Other Airflow 2 version" selected, which one?

What happened?

Looks like API authentication does not work with main version of airflow in breeze. The API calls are refused with 401 HTTP authentication error.

What you think should happen instead?

The client should authenticate with basic_auth.

How to reproduce

When you test Python client with https://github.com/apache/airflow-client-python/blob/main/dev/test_python_client.py (and earlier configure the webserver with:

auth_backends = airflow.api.auth.backend.session,airflow.api.auth.backend.basic_auth

the webserver refuses the connection with:

[2023-12-22T22:06:59.292+0000] {security_handler_factory.py:382} INFO - ... No auth provided. Aborting with 401.
                                                                                                                                                  │127.0.0.1 - admin [22/Dec/2023:22:06:59 +0000] "GET /api/v1/config HTTP/1.1" 401 124 "-" "OpenAPI-Generator/2.7.3/python"

This is the same for apache-airflow-client==2.7.3 and apache-airflow-client==2.8.0 .

When you use --use-airflow-version==2.8.0, it works just fine, so the problem seems to be coming from some recent changes in main.

Interesting ... When I run Airflow using Breeze (breeze start-airflow --skip-asset-compilation --backend postgres), I can successfully get the list of DAGs by calling the API http://localhost:28080/api/v1/dags in Postman using Basic auth

Hmm. let me try again. Maybe that was something I made mistake about (though I did it a the time I verified Python client and this is where I found it).

Yep. Can't reproduce. It works just fine in main. Must have been some mistake I've done (or something was fixed since in main :D ).

Sorry for the noise.
