sending part through remote event

[timber maple]

so i'm unable to send parts through remote events, it just returns nil.
this is not good because im building a rocket launcher system and i need to let the client know which rocket to tween where because server tweens are inefficient (and don't look good)
so how can i let the client know the needed rocket?

show script

[timber maple]

server

function module.updateClient(rocket,origin,dir,targetPos)
    serverToClientLib.updateRocket:FireAllClients(rocket)
end

[timber maple]

client

events.updateRocket.OnClientEvent:Connect(function(rocket)
    print(rocket)
end)
