Webserver Session ID Already Exists & OAuth Problems

[ahipp13]

Hi Airflow Community,

My co-worker and I have been struggling all week to figure out a problem we are having with our airflow instance and are looking anywhere for help.

For background, we are running airflow 2.4.3 on Kubernetes using the 8.6.1 Airflow Community Helm Chart (https://github.com/airflow-helm/charts/tree/main/charts/airflow) and we are using a postgreSQL DB running on an external server as our database.

To start, we were previously running Airflow 2.2.5 and everything was running smoothly, including the OAuth we had implemented. We then upgraded our helm chart and airflow version to 2.4.3, and our OAuth implementation broke. When we try to load the webserver login page we get session id errors in the logs of the webserver pod (Those logs are down below). Along with that, it will load the page, but it will be a different weird style and look with every refresh:

When you hit the login button, these logs pop up:
[2022-11-23 15:58:07,072] {views.py:659} ERROR - Error authorizing OAuth access token: mismatching_state: CSRF Warning! State not equal in request and response. ││ airflow-web [2022-11-23 15:58:07,072] {views.py:659} ERROR - Error authorizing OAuth access token: mismatching_state: CSRF Warning! State not equal in request and response.

And then it brings you back to the login screen where you again get the same errors I talked about before. I do not know if these errors are related or not. Any interesting note here is if we turn off OAuth and go to the default webserver_config, everything works just fine. Our implementation of the webserver_config is down below.

If anybody could help give answers as to what you think is going on or give tips on how to debug that would be greatly appreciated. This is my first time posting so if any other additional info is needed please let me know. Thank you

Hello Airflow community,

I'm currently facing the same issue as mentioned above. I have configured airflow 3.0.6, celery executor, postgressql DB, using FAB OAuth. Currently testing it out on a VM. Everything was running fine but the VM got rebooted in the weekend and now when I start the api-server and try to access the UI, it gives be the same error as mentioned above by @ahipp13 ((psycopg2.errors.UniqueViolation) duplicate key value violates unique constraint "session_session_id_key").
Any suggestions, workarounds, resolution would be appreciated.
