Error code 141 with getNativeBalance

i seem to get an error when trying to get the balance from current address with this code,
help please

getBalances = async() => {
    const ropstenbalance = await Moralis.Web3API.account.getNativeBalance({chain: "ropsten"});
    console.log(ropstenbalance.balance / 1e18);


you need to be authenticated for that to work, so that it know from where to get the user address

still does not work :frowning:

you can provide that address parameter if you want, it doesn’t look like you are authenticated there

hmm it worked when i provided the address, thankx mate
