These DAGs don't work on main:

  File "/usr/local/lib/python3.8/site-packages/jinja2/runtime.py", line 857, in _fail_with_undefined_error
    raise self._undefined_exception(self._undefined_message)
jinja2.exceptions.UndefinedError: '***.utils.context.InletEventsAccessors object' has no attribute 's3://output/1.txt'

Sorry, clicked the wrong button in the wrong window (don’t open too many things in your browser kids…)

I’ll fix the issue above in a separate PR.
