Getting the testnet balance is not working anymore

[elisabeth0bangoura]

Getting the balance with an ETH Testnet Wallet is not working anymore.
But the ETH Mainnet is still woking.

//My Code

const GetWalletInfo = async () => {

const account = new CryptoAccount(PrivKey, {
network: "goerli",
});

/* Print Balance */
console.log(await account.getBalance("ETH"));

}

GetWalletInfo()

// Console Error

    var error = new Error(message);
                ^
