How do I get this OrderedDataStore to work?

So i've been testing and testing but for some reason I get this error

local PurchaseHistory = game:GetService("DataStoreService"):GetOrderedDataStore("DevProducts")
PurchaseHistory:SetAsync(player.Name, "Premium Session Pass")

"player" value "IS" Defined It "IS" in a "Script" not "LocalScript"

In the output for the Dev-Console in online-game it says "Value is not allowed" and it's referring to "(player.Name, "Premium Session Pass")" Premium Session Pass string I'm truly unsure what to do about this

wait(.50)
print("GO ON WIKI BEFORE YOU GO ON THIS!")
