Describe the bug

I'm running in wsl and encountered this issue while running tests for an audit. Foundryup didn't fix the issue. Non fork tests seem to be running fine. Providing console output here.

 forge test --mt testCreationFeeSetter

@Abelaby can you provide code sample to reproduce? thank you

[yash-atreya]

@Abelaby can you also confirm whether you're using a WebSocket URL?

Hi @grandizzy ,

Using this script

// SPDX-License-Identifier: MIT

pragma solidity 0.8.10;

import {Test} from "forge-std/Test.sol";

contract ForkTest is Test{

    address internal constant wethAddress = 0xC02aaA39b223FE8D0A0e5C4F27eAD9083C756Cc2;
    IWETH weth;

    function setUp() public{
        
        vm.createSelectFork(
           "mainnet"
        );
        weth = IWETH(wethAddress);
    }

    function testDepositWETH() public{
        address alice = makeAddr("alice");
        vm.deal(alice, 1 ether);

        vm.startPrank(alice);
        IWETH(weth).deposit{value: 1 ether}();
      
    }
}

interface IWETH{
    function deposit() external payable;
    function withdraw(uint wad) external;
    function balanceOf(address owner) external view returns (uint);
}

I'm able to reproduce the issue, I've added my rpc in .env file. And running forge test --mt testDepositWETH -vvvv gives me the issue.

One thing I've noticed is that, this happens only when using public rpc like wss://ethereum-rpc.publicnode.com , wss://sonic.callstaticrpc.com , wss://ws.json-rpc.evm.iotaledger.net. Its perfectly fine if I use my private rpc from providers like alchemy.

@yash-atreya yes I was, seems like that was the issue.
