Call uniswap function with Vyper and report an error

Smart Contracts
1

I'm using vyper to write a contract that can call Uniswap to add liquidity, I use the function of raw_call, but it doesn't seem to work, the contract is deployed on rinkeby, I don't know what's going on, is there something wrong with my code, please help I pointed out that I am a newbie and I really need help

# @version ^0.2

from vyper.interfaces import ERC20

interface UniswapV2Router02:
    def factory() -> address: nonpayable
    def addLiquidityETH(
        token: address,
        amountTokenDesired: uint256,
        amountTokenMin: uint256,
        amountETHMin: uint256,
        to: address,
        deadline: uint256
    ) -> uint256[3]: nonpayable
