> In certain circumstances, such as in more complex DAGs where users utilize helper functions to add tasks, it may be possible to get into a condition where effectively there is a nested DAG context using the same DAG. When this happens, exiting both contexts does not reset `_CONTEXT_MANAGER_DAG`.
> This is especially problematic because the problem is seen in a later DAG, and the source of the error is not apparent.
