I am tring to test the meltano-airflow schedules. I followed the steps in the documentation to set it up. I have a docker-compose that starts two services: airflow scheduler and airflow webserver. When I trigger the DAG I get the following error:

[2023-01-24 16:27:20,369] {subprocess.py:63} INFO - Running command: ['bash', '-c', 'cd /project; .meltano/run/bin run tap-postgres--cudibi target-bigquery:run']

[2023-01-24 16:27:25,718] {subprocess.py:82} INFO - Command exited with return code 1

When I run the command by-hand inside the same docker container it works\. How can I debug this error? The log is not informative
