Need Help With Datastores

Help and Feedback Scripting Support

I’m trying to make a system where the player can buy things, like weapons, kill sounds, etc… The issue is, while I was trying to make a way to communicate between a server script and module script to trade the players item data (The data that holds all of the items that the player owns), It said that I could not submit a dictionary to a datastore.

104: Cannot store Dictionary in data store. Data stores can only accept valid UTF-8 characters.

I’m not sure what else to do so that I can save the players owned items like Kill Sounds (Which are located in the Player’s Player Object) and Weapons (Which is located in the Store and there Backpack). Does anyone know anything else I can do as an alternative to this?

Here’s the scripts

ServerScript / Datastore Script

You can use HttpService:JSONEncode to convert the dictionary to a string.

-- Services
local HttpsService = game:GetService("HttpsService")

-- Encode
local Encode = HttpsService:JSONEncode(playerItemTable)
playerItemData:SetAsync(player.UserId, Encode)

Note: You will have to use JSONDecode when you load the data back in.

local Decode = HttpsService:JSONDecode(playerItemData:GetAsync(player.UserId))

check to make sure the things in ur datastore arrays are only strings, numbers and booleans cuz datastore doesnt support roblox-only stuff like vector3s or ingame objects

Save it as a string.
game:GetService("ReplicatedStorage"):WaitForChild("Weapons"):WaitForChild("Classic Bomb").Name

that is probably ur error because roblox datastore does not store objects
