Every error is an obstacle that gets in the way of what users are trying to do. A reliable system detects unexpected or unwanted events, tries to gracefully recover from them, and finally warns the user about it.

Think carefully about the message, ie. what caused it and who will read it. A good error message helps the user solve the problem and move on. An unhelpful message can mean the difference between continuing or giving up.
