Review Comment:
IMO an HTTP 500 response (which will be the result of throwing a
`ConnectException` here) is more warranted in this place since we've already
checked to see that the plugin type is recognized on the worker by this point.
If things break here, it's more likely that the worker or one of its plugins is
set up or packaged incorrectly than that the user issued a bad request.
