I have a problem with the deployment of the BigQueryToMySqlOperator operator. The prolem is that the DAG does not replace the operator I defined, it tries to connect with the default one (‘mssql_default’). This is strange because the database connection variable works correctly on the other operator in this DAG.
What could be the reason for this action? Has anyone perhaps faced similar behaviour and solved it?
I have ruled out:
-
an error in the DAG
-
an error with the connection in the Airflow UI
expects the defined value to be substituted for mysql_conn_id
