Same core issue as https://github.com/apache/airflow/issues/23621. >This logic already exists; a @task-decorated task calls get_unique_task_id, which calls task_group.child_id. The root cause will be deeper than this. As far as I can tell this is not correct, this is the reason I found back when I opened it: > At the end of the day it seems that > ``` > if task_group: > self.task_id = task_group.child_id(task_id) > ``` > Is only executed by inheritors of `BaseOperator`. `MappedOperator` does not inherit from it so it never does execute the line that would prefix correctly the task_id, hence the duplicate key error thrown later, when `self.dag.add_task` is called. Maybe a simple fix would be to add those two lines to `MappedOperator` too, although there are other places that fiddle with the task_id. -- This is an automated message from the Apache Git Service.
