Describe your issue

When you set a title that goes over a character limit, /settitle's response's Title update failed! Are you missing the required scope?. While not documented in https://dev.twitch.tv/docs/api/reference/#modify-channel-information, when a title's exceeds 140 characters, you receive the following error. An alternative to requesting here could be to set a client side limit, as there's no way to set titles longer than this, no matter the API.

{
	"data": [],
	"error": "Bad Request",
	"message": "Title is too long.",
	"status": 400
}
