Why is "v.Value" nil? if I'm using "DataStore: GetAsync (UserId, Data)?

OUTPUT:

v.Value = nil v.key = 266839***

• DataStore request was added to queue. If request queue fills, further requests will be dropped. Try sending fewer requests.Key = 266839***

Why is "v.Value" nil? if I'm using "DataStore: GetAsync (UserId, Data)
