Review comment:
This error is already handled in the Webserver:
https://github.com/apache/airflow/blob/10b8ecc86f24739a38e56347dcc8dc60e3e43975/airflow/www/views.py#L883-L890
i.e we just ask users to run it via a CLI instead.
The `flash` message is so that they know where to look for i.e. run it using
the CLI
The `ExternalTaskMarker` does it cause failure in Scheduler or Webserver
