--[=[
	Shorthand for `Promise:andThen(nil, failureHandler)`.

	Returns a Promise that resolves if the `failureHandler` worked without encountering an additional error.

	:::warning
	Within the failure handler, you should never assume that the rejection value is a string. Some rejections within the Promise library are represented by [[Error]] objects. If you want to treat it as a string for debugging, you should call `tostring` on it first.
