无法使用 Maticjs 通过 POS Bridge 桥接部署的 ERC20 令牌，出现此错误“执行已恢复：ERC20：批准到零地址”

Question

这是我的代码，我还在 approve function 中添加了选项，其中包含从、到、gasLimit，但这对我也不起作用

const { POSClient, use } = require('@maticnetwork/maticjs');
const { Web3ClientPlugin } = require('@maticnetwork/maticjs-web3');
const HDWalletProvider = require('@truffle/hdwallet-provider');
require('dotenv').config();

use(Web3ClientPlugin);

async function getPOSClient() {
    const posClient = new POSClient();
    return await posClient.init({
        network: 'testnet',
        version: 'mumbai',
        parent: {
            provider: new HDWalletProvider(
                process.env.PVT_KEY,
                process.env.GOERLI_RPC
            ),
            defaultConfig: {
                from: process.env.FROM_ADDRESS,
            },
        },
        child: {
            provider: new HDWalletProvider(
                process.env.PVT_KEY,
                process.env.MUMBAI_RPC
            ),
            defaultConfig: {
                from: process.env.FROM_ADDRESS,
            },
        },
    });
}

async function approveToken() {
    const posClient = await getPOSClient();
    // console.log('🚀 ~ file: index.js:36 ~ approveToken ~ posClient', posClient);

    const erc20Token = posClient.erc20(process.env.ROOT_TOKEN, true);

    const result = await erc20Token.approve('1000');

    const txHash = await result.getTransactionHash();
    console.log('txHash', txHash);

    const receipt = await result.getReceipt();
    console.log('receipt', receipt);
}

approveToken();

我在批准令牌时遇到的错误，

Error: execution reverted: ERC20: approve to the zero address
0x08c379a00000000000000000000000000000000000000000000000000000000000000020000000000000000000000000000000000000000000000000000000000000002245524332303a20617070726f766520746f20746865207a65726f2061646472657373000000000000000000000000000000000000000000000000000000000000

我还从多边形标记映射器门户映射了标记。 请提供您的反馈

当您尝试将 ERC20 令牌批准到零地址时，会发生此错误。

假设批准接口是approve(spender, amount)我相信如果你将批准的地址添加到此调用const result = await erc20Token.approve(ADDRESS,'1000'); 这个问题将得到解决。
