nicnguyen3103 opened a new issue #22338:
URL: https://github.com/apache/airflow/issues/22338


   ### Apache Airflow version
   
   2.2.4 (latest released)
   
   ### What happened
   
   I was performing update for my swarm cluster from 2.2.2 to 2.2.4. After airflow db upgrade, both worker and scheduler can start just fine but the airflow webserver returns error: invalid command 'webserver'. 
   
   I exec into the worker container and try to start the webserver manually from there to reproduce the issue. Here is the screenshot from the CLI of the worker container when I try to start the webserver there 
   ![Screenshot from 2022-03-17 07-54-44](https://user-images.githubusercontent.com/46189714/158809735-1e6513d2-f6be-4363-99b0-af2013e457e0.png)
   
   
   
   ### What you think should happen instead
   
   I have no idea how to fix this issue as the airflow webserver start but then stop to yield command error, which is quite weird. 
   
   ### How to reproduce
   
   here is the command in the dockerfile for a clean airflow setup on my side
   
   RUN . $AIRFLOW_VENV/bin/activate && pip install 'apache-airflow[mysql,amazon,celery,papermill,ssh]==2.2.4' --constraint "https://raw.githubusercontent.com/apache/airflow/constraints-2.2.4/constraints-3.8.txt"
   RUN . $AIRFLOW_VENV/bin/activate && pip install -r $HOME/requirements-extend-airflow.txt
   
   with requirements-extend-airflow.txt contains 
   
   `apache-airflow[statsd]
