RuntimeError: We have now disallowed the calling of declareUniversal.
For future reference, use newUniversal
I fixed this locally just by changing the two "declareUniversal"
mentions to "newUniversal", but then it gives me a different error
which I'll send as a followup bug since it's probably a distinct bug.
