How to get the address balance of SRC20,SRC721

How to get the address balance of SRC20,SRC721 users

Cannot get a value using get_asset_balance

 let (instance, instance1, contract_id, wallet, wallet1) = get_contract_instance().await;
let balance: u64 = wallet.get_asset_balance(&asset).await.unwrap();
    println!("balance: {:?}", balance);
 

Hey @lopo1, its kinda strange, can you please try getting all the balances using .get_balances() method docuemented here and see what its output is?
also can you share the output for fuelup show from your terminal?
