I’d like to add that performance-wise, you should cache the results of :GetPropertiesOfClass() because it doesn’t do that internally and is quite slow.

local ReflectionService = game:GetService("ReflectionService")

local classPropertiesCache = {}

local function cacheClassProperties(className : string) : ()
	local cachedProperties = {}
	
	for _, v in ReflectionService:GetPropertiesOfClass(className) do
		cachedProperties[v.Name] =  v
	end
	
	classPropertiesCache[className] = cachedProperties
end

local function safeRead(instance : Instance, property : string) : any
	if not classPropertiesCache[instance.ClassName] then
		cacheClassProperties(instance.ClassName)
	end
	
	local hasProperty = classPropertiesCache[instance.ClassName][property] ~= nil
	if hasProperty then
		return instance[property]
	end
	
	return nil
end
