Which practice would have caught the error early?

Answer: Verify the request shape on the Messages API first, since batch params are checked at the end
The batch docs note that validation of each request's params happens asynchronously and errors are returned only when processing of the entire batch has ended, so the recommended safeguard is to verify the request shape against the Messages API first. The results_url stays null until processing ends.
