Returns:
Promise<any>
the deserialized stored value, or undefined when the key is absent or expired
Remarks
A stored null is returned as null and is therefore distinguishable from a miss; a stored undefined is not. Callers that must tell "cached as empty" from "not cached" should store an explicit sentinel rather than undefined.
