// Init Contract
  const [nusicContract, setNusicContract] = useState();
  useEffect(() => {
    (async () => {
      setNusicContract(
        await window.tronWeb.contract().at(nusicContractAddress)
      );
    })();
    return () => {

Here is the answer for this when you deploy you contract on testnets but your wallet is in mainnet

then we can’t load the contract but I guess TRON not returns right error message

so whenever you are using above code PLEASE remember that you are on Right NETWORK

in my case my deployed contract are on NILE Testnets and my wallet is in MAINNET

I fix this issue by using this code

if (!nusicContract) {
toast.error(“Please switch to NILE testnet”);
setLoading(false);
return;
}

change message according to you use case
you can always ping me over here or twitter if you need any help
