> Airflow tried to renders all the values passed to template_fields. In your case as your are using `EmrAddStepsOperator`, it's template_fields are `['job_flow_id', 'job_flow_name', 'cluster_states', 'steps']` > > **Source Code**: > > https://github.com/apache/airflow/blob/47c6657ce012f6db147fdcce3ca5e77f46a9e491/airflow/providers/amazon/aws/operators/emr_add_steps.py#L48 > > This was added by #8572 > > You can fix these in 2 ways: > > 1. Bypass this by adding an extra space after `.json` example `"s3://dummy/spark/application.json "`. This works because Airflow looks for each element in the Iterable to find if the string ends in `.json` > 2. Subclass `EmrAddStepsOperator` and override the `template_ext` field. Example: > > ```python > class FixedEmrAddStepsOperator(EmrAddStepsOperator): > template_ext = () > ``` > > and then you can use this Operator: > > ```python > proc_step = FixedEmrAddStepsOperator( > task_id='process_data', > job_flow_id="{{ task_instance.xcom_pull(task_ids='launch_emr_cluster', key='return_value') }}", > aws_conn_id='aws_default', > steps=STEPS, > ) > ``` @kaxil this solution works but seems like a hack to me.
