Uninformative error messages

Sometimes when submitting a form, an error message that provides no useful information is generated... see example below. I'm not asking for help w/ this particular error -- I can muddle through solving it -- but can't Creator be made to always provide some kind of info about any given error so it's not just a vague uninformative error message? Surely at the time the error is thrown, the compiler knows what threw the error, or at least some contextual information that would be useful.

Thanks.
