Invalid command error

[renzhe-brian]

Hello community,

We are experiencing some weird error with our setup in all of our environments. Airflow runs well in our GKE environments, there's no issue accessing webserver or scheduling jobs. However, if we enter any of the running pods, and we run airflow commands, we see invalid command error. Here are two examples:

$ airflow dags list
usage: airflow [global_opts] cmd1 [cmd1_opts] [cmd2 [cmd2_opts] ...]
   or: airflow --help [cmd1 cmd2 ...]
   or: airflow --help-commands
   or: airflow cmd --help

error: invalid command 'dags'

$ airflow scheduler

We experienced the same issue with old versions as well, we thought upgrading to latest versions might solve the problem. This is our current version

Airflow version: 2.7.3
airflow-helm/charts version: 8.8.0
