I am managing a Google Cloud Composer environment which runs Airflow for a data engineering team. I have recently been asked to troubleshoot one of the dags they run which is failing with this error : [12:41:18,119] {credentials_utils.py:23} WARNING - [redacted-name] connection ID not available, falling back to Google default credentials
The job is basically a data pipeline which reads from various sources and stores data into GBQ. The odd part is that they have a strictly similar Dag running for a different project and it works perfectly.
I have recreated the .json credentials for the service account behind the connection as well as the connection itself in Airflow. I have sanitized the code to see if there was any hidden spaces or so.
My knowledge of Airflow is limited and I have not been able to find any similar issue in my research, any one have encountered this before?
