"failed transfer to address." during std::token::mint_to_address call

fuel · June 19, 2023, 4:19pm

Hi there, I’m implementing a token standard but have a problem with mint_to_address

something strange is happening, while I was trying to run spark on beta-3, I installed the latest toolchain and now the mint token in the test that worked before does not work for me. The same error in my last token standard which has not changed since December. I just made an example of an issue with a new token standard to make it easier to perceive

I have admin’s mint function in my standard:

github.com

compolabs/src-20/blob/master/contarct/src/main.sw#L46


      
                  DECIMALS
              }
              fn name() -> String {
                  NAME.unwrap_or(String::new())
              }
              fn symbol() -> String {
                  SYMBOL.unwrap_or(String::new())
              }
          
          
    #[storage(read, write)]
              fn _mint(amount: u64, recipient: Address){
                  assert(msg_sender().unwrap() == Identity::Address(OWNER));
                  storage.total_supply.write(storage.total_supply.try_read().unwrap_or(0) + 1);
                  mint_to_address(amount, recipient);
              }
          }

And have a simple test:

github.com

compolabs/src-20/blob/master/contarct/tests/harness.rs#L12


      
              prelude::{abigen, Contract, LoadConfiguration, TxParameters},
              test_helpers::{launch_custom_provider_and_get_wallets, WalletsConfig},
          };
          
          
abigen!(Contract(
              name = "TokenContract",
              abi = "out/debug/FRC20-abi.json"
          ));
          #[tokio::test]
          async fn main_test() {
              let config = WalletsConfig::new(Some(5), Some(1), Some(1_000_000_000));
              let wallets = launch_custom_provider_and_get_wallets(config, None, None).await;
              let admin = &wallets[0];
              let alice = &wallets[1];
          
          
    let configurables = TokenContractConfigurables::new()
                  .set_DECIMALS(9)
                  .set_NAME(None)
                  .set_SYMBOL(None)
                  .set_OWNER(admin.address().into());

But when I run this test I have this error

Hey, I was able to get the tests to pass by adding append_variable_outputs(1) to the contract call.

    contract_instance
        .methods()
        ._mint(100, alice.address().into())
        .append_variable_outputs(1)
        .call()
        .await
        .unwrap();

Let me know if that solves the problem!

fuel · June 21, 2023, 9:41am

Exactly, that’s how it works… Sorry guys, that was super dumb of me.

david · June 21, 2023, 10:19am

No worries, I’ve run into the same thing before

IMO we need a better error message to hint at this

fuel · June 21, 2023, 4:28pm

agree, thanks a lot for your help
