Getting config_filepath error while using dag factory on GCP Cloud Composer

[manishnanda]

After adding dag-factory as part of PYPI packages in GCP Cloud composer and corresponding dag and yml file into DAGs folder getting broken DAG on Airflow UI with below error:-

Broken DAG: [/home/airflow/gcs/dags/dag_gcp_test.py] Traceback (most recent call last):
File "/opt/python3.8/lib/python3.8/site-packages/dagfactory/dagfactory.py", line 32, in init
DagFactory._validate_config_filepath(config_filepath=config_filepath)
File "/opt/python3.8/lib/python3.8/site-packages/dagfactory/dagfactory.py", line 45, in _validate_config_filepath
raise Exception("DAG Factory config_filepath must be absolute path")
Exception: DAG Factory config_filepath must be absolute path

Please help in providing root cause and resolution for this as require to move the Airflow setup of important project from local to GCP as having many DAGs build through dag-factory
