Opening a player document

This is an example of how to open a document for a DocumentStore that deals with player data. Opening a session-locked document will enable autosaves. At the time of writing, these happen every 150 seconds. The following code should run on Players.PlayerAdded:

local document = store:GetDocument(tostring(player.UserId))
local result = document:Open()

-- DocumentService retries 5 times over 16 seconds, so it is safe to steal
-- after a failed `:Open`!
if not result.success and result.reason == "SessionLockedError" then
   document:Steal()
   result = document:Open()
end

if not result.success then
   if result.reason == "BackwardsCompatibilityError" then
       player:Kick(
           "You joined an old server which does not support your saved data."
               .. "Please try joining another server. If this persists, contact a developer."
       )
   end

   if result.reason == "RobloxAPIError" then
       player:Kick("Failed to load data due to a Roblox service issue. Try again later.")
   end

   player:Kick(
       `Failed to load data: {result.reason}. Please screenshot this message and report it to a developer.`
   )

   return false
end

You should close documents when a player leaves. Note that I have not created a player documents table. You should use :GetDocument to retrieve the document - there is usually no need to create a table to reference your player documents. See the API reference for GetDocument for information on when documents are garbage collected.
