RNHTTR commented on issue #23315: URL: https://github.com/apache/airflow/issues/23315#issuecomment-1112594218
I've found the issue. Task expansion creates a `MappedOperator`, which interestingly inherits from `AbstractOperator` and not `BaseOperator`. `airflow dags show` ultimately users `[dot_renderer.py](https://github.com/apache/airflow/blob/main/airflow/utils/dot_renderer.py#L117-L118)` to draw the DAG, and it checks that each node is either a `TaskGroup` or a `BaseOperator`, thus the error. I'll put together a fix, a test, and submit a PR. -- This is an automated message from the Apache Git Service.
