I have configured Airflow with rabbitmq broker, the services:
airflow worker airflow scheduler airflow webserver are running without any errors. The scheduler is pushing the tasks to execute on default rabbitmq queue:
Even I tried airflow worker -q=default - worker still not receiving tasks to run. My airflow.cfg settings file:
