---------------------------------------
Summary: TriggerDagRunOperator Forces JSON
Key: AIRFLOW-4007
URL: https://issues.apache.org/jira/browse/AIRFLOW-4007
Project: Apache Airflow
Issue Type: Bug
Components: DagRun
Affects Versions: 1.10.0
Reporter: Dillon Johnson
The project has seemingly forced the TriggerDagRunOperator `conf` to allow JSON
only. This is different than how it was previously where I was allowed to pass
class instances without any special handling.
https://github.com/apache/airflow/blob/master/airflow/operators/dagrun_operator.py#L94
https://github.com/apache/airflow/blob/master/airflow/api/common/experimental/trigger_dag.py#L65
These are the 2 snippets that enforce this.
This is different than the previous behavior as well as XCOMs. I can pass my
class instance object through XCOM, but I cannot pass it via conf with
TriggerDagRunOperator. If this is the intended behavior, what's the feasible
workaround for this?
Currently, I'm working around this by creating a custom operator with the old
code that allows class instances to be passed in the conf.
