Can't store dictionary in datastore

I’m trying to make a model serializer/deserializer that saves, but it’s not letting me save dictionaries.

local ss = {}
ss.__index = ss

local dss = game:GetService("DataStoreService"):GetDataStore("Serializer")

function ss.new(model : Model, save : boolean?)
	local self = setmetatable({model = model}, ss)
	if save ~= nil and save == true then self.save = true end
	return self
end

function ss:serialize()
	local objs = self.objects
	local serialized_objs = {}
	for _,v in pairs(self.model:GetChildren()) do
		serialized_objs[v.Name] = {
			ClassName = v.ClassName,
			Name = v.Name,
			Size = v.Size,
			Position = v.Position,
			Transparency = v.Transparency,
			Parent = v.Parent
		}
	end
	self.serialized_objs = serialized_objs
	if self.save then dss:SetAsync("Serializer", self.serialized_objs) end --where the error occurs
	--print(self.serialized_objs)
end


function ss:deserialize()
	assert(dss:GetAsync("Serializer"), "Nothing to deserialize")
	assert(self.save, "Save mode not enabled")
	print(dss:GetAsync("Serializer"))
	--[[
	local m = Instance.new("Model")
	for _,v in pairs(dss:GetAsync("Serializer")) do
		m.Name = v.Parent.Name
		local p = Instance.new(v.ClassName)
		p.Name = v.Name
		p.Size = v.Size
		p.Position = v.Position
		p.Transparency = v.Transparency
		p.Parent = game.Workspace[v.Parent.Name]
	end
	]]
end

return ss

You’re not serializing the Vector3s in the Size and Position Properties, and you’re not serializing the instance in the Parent property.

if im correct you just need to use jsonencode to turn the dictionary into a string then save it and when you want to get the data then just use jsondecode to turn it back into a dictionary

hope that helps
