GetSortedAsync's IsFinished not returning true on the last page

[iamEvanRBLX (iamEvan)]

OrderedDataStore:GetSortedAsync() is not returning true on the last page.
This causes the while loop to run endlessly, causing rate limits.

Expected behavior

Pages.IsFinished to return true when the last page has been reached.

Repro Code

local orderedDS = game:GetService("DataStoreService"):GetOrderedDataStore("TestDS")

orderedDS:SetAsync("Test1", 10)
orderedDS:SetAsync("Test2", 1)
print("setted")

task.wait(5)

local pages = orderedDS:GetSortedAsync(true, 100)

while true do
	local breaking = false

	local page = pages:GetCurrentPage()
	for _, data in ipairs(page) do
		local key:string = data.key
		local exist:number = data.value

		print("key", key)
	end

	if pages.IsFinished then
		-- We've reached the last page of results
		breaking = true
	else
		-- There are more pages of results
		pages:AdvanceToNextPageAsync()
		print("advancing, IsFinished", pages.IsFinished)
	end

	if breaking then
		break
	end
end

I can reproduce this issue using the command bar:

This is completely breaking my game right now.

This is breaking my game as well.
Stumbling through it, I’ve come to the same conclusions when trying to figure out why my datastores are breaking.

Datastore Limits

@LLukasVx @LiamSternenstei1 The code below is taken directly from the DataStores Documentation page. If you put this into a fresh place and run the code, it endlessly advances. Printing the first 3 characters, then the next 2, and then repeating. Does this seem normal to either of you? I believe my code is experiencing the same problems. I thought if you were at the last page and try to advance, it would error. However, it seems to be going back to the first page. pages.IsFinished seems to a…

Thanks for the report! Just to confirm, we are investigating this issue.

It broke my game too, i spent lots of hours but couldnt find any solution. This literally zeroed my playerbase and still there isnt any update, I think this is a really critical issue and should be fixed like right now. I really wish engineers will fix it very soon

Any update on this bug? This is causing lots of issues.

I guess that’s still a problem

It seems like that this bug no longer occurrs on newly created ordered datastores even after saving 10,000 keys and then removing them however the bug still happens on old ordered datastores.
After investigating what the backend responds on a broken and a not broken datastore these are my findings:
Not Broken Ordered Datastore

Broken Ordered Datastore

The lastEvaluatedKey being an empty string is probably messing with robloxs check to determine if it IsFinished
