Hmm thanks for the clarification. 
Version 4.17.0 would have finished its Cloud rollout by last Thursday (7/2), so I certainly expect the Vite fix to have been live as of Monday. I don't see any of the same errors during your most recent MCP session, though, which is promising. It actually looks like you successfully published - can you confirm?
I think most of the additional debugging that I'd like to do would be better done on a live call. Are you able to join our scheduled Office Hours?
