Script breaks when invoking bindable function

for i,v in pairs(char:GetChildren()) do
    if v:IsA("BasePart") then
        v.Touched:Connect(function(hit)
            print(DataEvent:Invoke("Get", "GridCells", tostring(hit.Parent.Name))) -- HERE
            print("wer")
            if hit:IsA("BasePart") and hit.Parent.Parent.Name == "Grid" and GridModule.GetState(tonumber(hit.Parent.Name)) == true then
                print(GridModule.GetState(tonumber(hit.Parent.Name)))
                ChangeBtn(true)
            elseif  hit:IsA("BasePart") and hit.Parent.Parent.Name == "Grid" and GridModule.GetState(tonumber(hit.Parent.Name)) == false then
                print(hit.Parent.Parent.Name)
                ChangeBtn(false)
            end
        end)
    end


end

I have no idea what I’m doing wrong here but the script just breaks when I invoke a bindable function. The Touched events don’t work and the output is empty. I’m not sure what I’m doing wrong here.

This is where I receive the invoke

local ServerData = {
	["GridCells"] = {}
}
local AddData = game:GetService("ReplicatedStorage"):WaitForChild("Remotes"):WaitForChild("ServerData")

AddData.OnInvoke = function(action, category, name, data)
	if action == "Add" then
		ServerData[category][name] = data
	elseif action == "Get" then
		print("Received")
		return ServerData[category][name]
	end
end
