Describe the bug

I would like to reopen the issue from here https://github.com/foundry-rs/foundry/issues/6579

I am not sure if the issue has been fixed because I am also getting hexadecimal custom errors.

To recreate the bug, please go to this repo here and use the command -> forge test --match-path test/scWETHv2.base.t.sol --match-test test_invest_basic -vv

#6579 was done for custom errors within setup, will check the scenario you hit

yep, I managed to recreate with the project above, the error is ErrorNotEnoughBalance thrown by the ERC20Bridged contract https://basescan.org/address/0x69ce2505CE515C0203160450157366F927243309 which is not an artifact created during test so the abi to properly decode error is not available - you can check this by for example adding error ErrorNotEnoughBalance(); in contract PriceConverter which is created during test run, it will output

Failing tests:
Encountered 1 failing test in test/scWETHv2.base.t.sol:scWETHv2Base
[FAIL. Reason: ErrorNotEnoughBalance()] test_invest_basic() (gas: 852945)

I see. Thank you so much. Can you please tell me how did you decode the error is ErrorNotEnoughBalance() from the hex code please? That was really amazing.

I took the code for failing contract and run forge inspect errors on it, see https://book.getfoundry.sh/reference/cli/forge/inspect?#forge-inspect You can also use forge selectors list https://book.getfoundry.sh/reference/cli/forge/selectors/list

(to get the code you can use forge clone or cast etherscan to download from verified contracts but you could only get the errors from failing contract, put in a local contract and run the command against)
