Hello Developers,

I would like to get all the player names from data store

-- datastore key example
--  global/1008722249

So, this is not a player userid, I checked it, now how do I get the player name?
Script:

local key = ds1:ListKeysAsync()
local keys = key:GetCurrentPage()
for i,v in pairs(keys) do
    print(v.KeyName)
end

Check the DevHub Page here

2 
local players = game:GetService("Players")
local val, dsInfo = DataStore:GetAsync("") --replace with some valid key
local userId = dsInfo:GetUserIds()[1]
local username = players:GetNameFromUserIdAsync(userId)

Check the values returned by the function: GetAsync()
