Script failed with no error information

[CaledoniaProject]

I'm playing this level: https://capturetheether.com/challenges/math/token-sale/

So I wrote the contract:

// SPDX-License-Identifier: UNLICENSED
pragma solidity ^0.8.13;

import "forge-std/Script.sol";
import "forge-std/Test.sol";

interface TokenSaleChallenge {
    function buy(uint256 numTokens) payable external;
    function sell(uint256 numTokens) payable external;
}

contract MyTokenScript is Test {
    TokenSaleChallenge target;

    function setUp() public {
        target = TokenSaleChallenge(0x271b62d633a78D7C2a309875F95aB2D3689B2c27);
    }

    receive() payable external {
        target.buy{value: 1 ether}(1);
    }

    function run() external {
        vm.startBroadcast();

        target.buy{value: 1 ether}(1);
        target.sell{value: 1 ether}(1);
    }
}

And launched forge with infura API:

# forge script --sender xxx --private-key xxx --fork-url https://rinkeby.infura.io/v3/xxx script/TokenSale.s.sol -vvvvv --broadcast

Script failed.
Error:
Script failed.

Anyone know why it fails?

I figured out, the test network is wrong, but forge didn't prompt anything

If the test network is wrong you likely interacted with an account with no code. The error here is a run-time error generated by Solidity, i.e. Solidity inserts either an extcodesize check (checking that the account has code) or an attempt to decode the return data of the function. So, it is Solidity that is reverting with no error: this is not really something we can check for, hence the lacking error message.

Understood.
