createError([status], [message], [properties])

var err = createError(404, 'This video does not exist!');

• status: 500 - the status code as a number
• message - the message of the error, defaulting to node's text for that status code.
• properties - custom properties to attach to the object

var err = new createError.NotFound();

• code - the status code as a number
• name - the name of the error as a "bumpy case", i.e. NotFound or InternalServerError.
