This was wrong. It was passing in a List[int] whereas the class signature expected User. I'm somewhat perplexed as to why Mypy didn't report this an error. See this Slack thread for details.

new_model = DuplicateDatasetCommand(item).run()
return self.response(201, id=new_model.id, result=item)

See the previous comment. I gather Mypy didn't barf because it was being passed List[int] as opposed to User per the class __init__ method.

Note, per here there's no need to specify [g.user.id] given that it defaults to the current user if not specified.

owners = self.populate_owners()
self._properties["owners"] = owners
