MultiversePlotCreator DAG support does not allow path-only field specification
As discovered here by @herdeanu, the MultiversePlotCreator
has a bug in the add_sac_transformation
helper function.
Bug behaviour
select_and_combine:
fields:
some_field_name: some/path
should be valid syntax, but it fails.
Workaround
Fall back to more explicit syntax
select_and_combine:
fields:
some_field_name:
path: some/path
Correct behaviour
The short syntax is possible.
