What version of Foundry are you on?

forge 0.2.0 (0b73b42 2024-08-05T00:19:50.130854000Z)

What command(s) is the bug in?

anvil; forge create SimpleStorage --private-key 0xac0974bec39a17e36ba4a6b4d238ff944bacb478cbed5efcae784d7bf4f2ff80; cast send 0x5FbDB2315678afecb367f032d93F642f64180aa3 "setValue(uint256)" 101 --private-key=0xac0974bec39a17e36ba4a6b4d238ff944bacb478cbed5efcae784d7bf4f2ff80

Operating System

macOS (Apple Silicon)

Describe the bug

When running cast send, if your tx reverts with a custom error, cast only displays:

Error: 
server returned an error response: error code 3: execution reverted: 

But no custom error (nor error, nor signature), which makes it super hard to debug.

Reproducible with the anvil's default private key with this contract:

// SPDX-License-Identifier: MIT
pragma solidity ^0.8.0;

contract SimpleStorage {
    uint256 private storedValue;

    event ValueChanged(uint256 newValue);

    error ValueTooHigh(uint256 providedValue, uint256 maxValue);

    function setValue(uint256 _newValue) public {
        if (_newValue > 100) {
            revert ValueTooHigh({ providedValue: _newValue, maxValue: 100 });
        }
        storedValue = _newValue;
        emit ValueChanged(_newValue);
    }

    function getValue() public view returns (uint256) {
        return storedValue;
    }

    function incrementValue() public {
        storedValue += 1;
        emit ValueChanged(storedValue);
    }

    function divideTenBy(uint256 _divisor) public pure returns (uint256) {
        require(_divisor != 0, "Cannot divide by zero");
        return 10 / _divisor;
    }
}

1. Run Anvil
2. forge create SimpleStorage --private-key 0xac0974bec39a17e36ba4a6b4d238ff944bacb478cbed5efcae784d7bf4f2ff80
3. cast send 0x5FbDB2315678afecb367f032d93F642f64180aa3 "setValue(uint256)" 101 --private-key=0xac0974bec39a17e36ba4a6b4d238ff944bacb478cbed5efcae784d7bf4f2ff80

see #8603

[grandizzy]

this is fixed now, showing

server returned an error response: error code 3: execution reverted: custom error 0x7a0e1985: ed, data: "0x7a0e198500000000000000000000000000000000000000000000000000000000000000650000000000000000000000000000000000000000000000000000000000000064

to see decode with project abis, then you can use
forge selectors find 0x7a0e1985

which will return

+-------+-------------------------------+------------+---------------+
| Type  | Signature                     | Selector   | Contract      |
+====================================================================+
| Error | ValueTooHigh(uint256,uint256) | 0x7a0e1985 | SimpleStorage |
+-------+-------------------------------+------------+---------------+

Please reopen if still an issue for you. thank you!
