EVM error

[heheboii11]

When trying to swap from WETH to MKR, I am getting EvmError. Giving the error log here and the code

//SPDX-License-Identifier: MIT

pragma solidity >=0.6.2 <0.9.0;

import {Test, console} from "forge-std/Test.sol";
import {IUniswapV2Router02} from "@uniswap/v2-periphery/contracts/interfaces/IUniswapV2Router02.sol";
import {IERC20} from "forge-std/interfaces/IERC20.sol";
import {IWETH} from "@uniswap/v2-periphery/contracts/interfaces/IWETH.sol";

contract UniswapTest is Test {
    IWETH public WETH = IWETH(0xC02aaA39b223FE8D0A0e5C4F27eAD9083C756Cc2);
    IERC20 public DAI = IERC20(0x6B175474E89094C44Da98b954EedeAC495271d0F);
    IERC20 public MKR = IERC20(0x9f8F72aA9304c8B593d555F12eF6589cC3A579A2);
    IUniswapV2Router02 public router = IUniswapV2Router02(0x7a250d5630B4cF539739dF2C5dAcb4c659F2488D);
    uint256 public amountIn = 1e18;
    address public user = makeAddr("user");

    function setUp() public {
        vm.deal(user, 10e18);
        WETH.deposit{value: 2e18}();
    }

    function testSwap() public {
        vm.startPrank(user);
        address[] memory path = new address[](3);
        path[0] = address(WETH);
        path[1] = address(DAI);
        path[2] = address(MKR);
        WETH.approve(address(router), amountIn);
        router.swapExactTokensForTokens(amountIn, 1, path, user, block.timestamp);
        uint256 amount = MKR.balanceOf(user);
        console.log("MKR:", amount);
    }
}

IWETH is the interface in the v2-periphery. I have modified that interface slighty so that it inherits IERC20

pragma solidity >=0.5.0;

import {IERC20} from "./IERC20.sol";

interface IWETH is IERC20 {
    function deposit() external payable;
    function transfer(address to, uint256 value) external returns (bool);
    function withdraw(uint256) external;
}

But the orginal IWETH doesnot inherits IERC20

This has been resolved, I forgot to transfer the WETH to the User

    function setUp() public {
        vm.deal(user, 10e18);
        WETH.deposit{value: 2e18}();
        WETH.transfer(user, 2e18);
    }
