MetaMask - RPC 错误：执行恢复，简单的 NFT 迷你 Dapp

Question

我正在构建一个简单的 NFT 铸造 Dapp 用于筹款。 我首先在 Polygon 测试网上部署了合约，然后在以太坊测试网 goerli 上部署了合约。 在整合的同时 ，我的智能合约前端使用 Ethers.js，我遇到了同样的错误。 我进行了研究并尝试了一些可用的解决方案，但仍然遇到相同的错误。

这是完整的仓库： https://github.com/DevABDee/WagmiPakistan您可以使用 live-Server 来运行应用程序，我使用的是简单HTML

我的 hardhat.config.js：

require("@nomicfoundation/hardhat-toolbox");
require("dotenv").config({ path: ".env" });

POLYGON_TESTNET_URL = process.env.POLYGON_TESTNET_URL;
GOERLI_TESTNET_URL = process.env.GOERLI_TESTNET_URL;
PRIVATE_KEY = process.env.PRIVATE_KEY;
ETHERSCAN_API_KEY = process.env.ETHERSCAN_API_KEY;

module.exports = {
  solidity: {
    version: "0.8.7",
    settings: {
      optimizer: {
        enabled: true,
        runs: 200,
      },
    },
  },
  networks: {
    matic: {
      url: POLYGON_TESTNET_URL,
      accounts: [PRIVATE_KEY],
      gas: 2100000,
      gasPrice: 8000000000
    },
    goerli: {
      url: GOERLI_TESTNET_URL,
      accounts: [PRIVATE_KEY],
      gas: 2100000,
      gasPrice: 8000000000
    }
  },
  etherscan: {
    apiKey: ETHERSCAN_API_KEY
  }
};

索引.js：

import { ethers } from "https://cdn-cors.ethers.io/lib/ethers-5.5.4.esm.min.js";
import {contractAddress, contractAbi} from  "./constants.js";

const mintBronze = document.getElementById('MintBronze');
const mintSteel = document.getElementById('MintSteel');
const mintGold = document.getElementById('MintGold');
const mintDiamond = document.getElementById('MintDiamond');
const mintPlatinum = document.getElementById('MintPlatinum');

mintBronze.onclick = MintBronze;
mintSteel.onclick = MintSteel;
mintGold.onclick = MintGold;
mintDiamond.onclick = MintDiamond;
mintPlatinum.onclick = MintPlatinum;

async function connect() {

    if (typeof window.ethereum !== 'undifined') {
        await window.ethereum.request({ method: "eth_requestAccounts" })
        console.log("Connected");
    } else {
        console.log("Get A Metamask Wallet");
    }

}

connect();

let provider = new ethers.providers.Web3Provider(window.ethereum)
let signer = provider.getSigner();
let wagmiPakistanContract = new ethers.Contract(contractAddress, contractAbi, signer)


async function MintBronze() {
    const mintBronze = wagmiPakistanContract.mintBronze();
    const Bronze = await mintBronze;
    console.log(`${Bronze} Minted`);
}
async function MintSteel() {
    const mintSteel = wagmiPakistanContract.mintSteel();
    const Steel = await mintSteel;
    console.log(`${Steel} Minted`);
}
async function MintGold() {
    const mintGold = wagmiPakistanContract.mintGold();
    const Gold = await mintGold;
    console.log(`${Gold} Minted`);
}
async function MintDiamond() {
    const mintDiamond = wagmiPakistanContract.mintDiamond();
    const Diamond = await mintDiamond;
    console.log(`${Diamond} Minted`);
}
async function MintPlatinum() {
    const mintPlatinum = wagmiPakistanContract.mintPlatinum();
    const Platinum = await mintPlatinum;
    console.log(`${Platinum} Minted`);
}

请帮帮我。 谢谢

调用合约时您没有发送任何以太币，因此msg.value为 0。以下是调用需要msg.value等于 0.001 以太币的 function 时发送以太币的方式（因为您在智能合约中定义的 function 需要msg.value为 0.001):

const mintBronze = wagmiPakistanContract.mintBronze({ value: ethers.utils.parseEther("0.001") });

与其他函数类似，语法为：

const mintSteel = wagmiPakistanContract.mintSteel({ value: ethers.utils.parseEther("0.002") });
const mintGold = wagmiPakistanContract.mintGold({ value: ethers.utils.parseEther("0.003") });
const mintDiamond = wagmiPakistanContract.mintDiamond({ value: ethers.utils.parseEther("0.004") });
const mintPlatinum = wagmiPakistanContract.mintPlatinum({ value: ethers.utils.parseEther("0.005") });
