It seems that this enum was, for whatever reason, unnamed. Naming it as DetectorType solved my problem.
I really don't know why the enum wasn't originally named, but someone else had the same error. The link below leads to a Page Not Found, but someone else did ask the same question (and probably deleted the post after solving it).

Thank you.
