MappedOperator determines how many downstream task instances to create by counting XCOMs associated with upstream mapped tasks. The current implementation assumes each upstream mapped task has a single XCOM. When upstream tasks push additional XCOMs beyond the default one then MappedOperator will generate too many downstream task instances. This change updates the XCOM counting query to only consider XCOMs with a key matching the `XCOM_RETURN_KEY` constant. closes: https://github.com/apache/airflow/issues/24487 -- This is an automated message from the Apache Git Service.
