Getting "Invalid data" with the getCode cheatcode

[ZeroEkkusu]

Gm, sers,

I can't get the getCode cheatcode to work

// SPDX-License-Identifier: Unlicense
pragma solidity 0.8.10;

import "ds-test/test.sol";
import "./ICheatCodes.sol";

contract MyContractTest is DSTest {
    CheatCodes cheats = CheatCodes(HEVM_ADDRESS);

    function setUp() public {}

    function testExample() public {
        bytes memory code = cheats.getCode("MyContract.sol:MyContract");
    }
}

Here's the output:

Running 1 test for MyContractTest.json:MyContractTest
[FAIL. Reason: Invalid data] testExample() (gas: 3369)

I also tried using "MyContract.sol", "src/MyContract.sol:MyContract", "../MyContract.sol:MyContract", and the full path, but got the same result.

LG! I've figured it out!

For some reason, doing foundryup does not actually update Foundry for me 🤔.
So I built it from source with:

cargo install --git https://github.com/gakonst/foundry --bins --locked

I tried testing again, and it works!

If foundryup is not working it's likely because which forge points to ~/.cargo, and not ~/.foundry. You can run either update the order in your $PATH or remove the binaries from the cargo dir with rm ~/.cargo/bin/forge && rm ~/.cargo/bin/cast && foundryup

Thank you, that fixed it!
