(DataStore) GetAsync errors nil value

#1

I’m working on a datastore which stores the value inside player:
I haven’t write the SetAsync yet but I can’t even load it:

	local data = {}
	local DS_Folder_DataStore = dss:GetDataStore("DS_Folder_DataStore")
	
	local emotesData = {}
	local DS_Folder_EmotesData = dss:GetDataStore("DS_Folder_EmotesData")

for i,v in pairs (plr.DataStores:GetChildren()) do
	if v then
		table.insert(data, {key = plr.UserId,data_name = v.Name, value = v.Value})
	end
end

for i,v in pairs (plr.emotesFolder:GetChildren()) do
	if v then
		table.insert(emotesData, {key = plr.UserId,data_name = v.Name, value = v.Value})
		print("data_name="..v.Name.."Value="..v.Value.."key=".. emotesData[i].key)
	end
end

for i = 1,#data do
	if data[i].data_name ~= nil and data[i].value ~= nil then
		plr.DataStores[data[i].data_name].Value = DS_Folder_DataStore:GetAsync(data[i].key)
	end
end

for i = 1,#emotesData do
	if emotesData[i].data_name ~= nil and emotesData[i].value ~= nil then
		plr.emotesFolder[emotesData[i].data_name].Value = DS_Folder_EmotesData:GetAsync(emotesData[i].key)
	end
end

For the First Datastore DS_Folder_DataStore works fine, however for the emotes one, it errors:

I have no clue why it happens when they are basically the same thing, they just use a different table and DataStore but their scenario are same.
For the values that DS_Folder_DataStore stores, they are all IntValue

For the values that DS_Folder_emotesFolder store, they are all Strings:

Is the value type actually the root cause of the problem? I don’t see a direct relationship between the value type and the DataStore.

What code specifically is at line 45? You haven’t specified that here and I’m not up for counting.

Oops, forgot to mention that
It’s the third column count from the bottom from the code that I provided

I don’t think it’s necessarily that the value types are different or anything. Your code assumes that a non-nil value will be retrieved on every GetAsync call and attempts to set it to a ValueObject’s value. Therefore, if there’s a nil in the DataStore, it attempts to set a value to nil.

I’d strongly recommend revising the code here to fetch first, verify values and then set.

I think it’s because IntValue will set to 0 when you attempt to set it to nil but not for StringValues? Thanks though, I’ll verify values first now.

Edit: Solved by:

if emotesData[i].data_name ~= nil and emotesData[i].value ~= nil and DS_Folder_EmotesData:GetAsync(emotesData[i].key) ~= nil then
