Middleware client should not crash app when client code is invalid

[irae]

I was during my normal developer flow, and I got a git conflict.

Git conflicts are pretty common workflow and they often break syntax. Here is what I got back:

I fully agree that we should log this error, and the stack is correct. But the last line shows that my server crashed with this change, which is something I would not expect to happen. It is not that bad, but workflow could be improved by console.error with colors and recovering transparently.
