Starting airflow with Docker - trigger ERROR

Question

I am new to Docker so I have followed the official guide here for running Airflow with it-https://airflow.apache.org/docs/apache-airflow/stable/start/docker.html

When I start Airflow all services with 'docker-compose up' in Ubuntu, I get "ERROR - Triggerer's async thread was blocked for ... seconds, likely by a badly-written trigger. Set PYTHONASYNCIODEBUG=1 to get more information on overrunning coroutines."

Any idea how to fix this issue is appreciated. Thanks,

This can be fixed by allocating more resources as mentioned here, by default docker allocates 2gb of memory and 4gb is needed.

You can follow this link for mac and link for Windows on how to change your resource allocation.

Also check your docker-compose version, you can do so by running docker-compose --version.
