“... is usually a typo” is your number-one clue here.   Did you, say, omit a quote-mark in a string a few lines back?   Did you typo something?   Look extremely carefully at the source-code in the immediate vicinity.   The author of that message is trying to tell you that it is probably a red-herring.
