在 Moralis 分叉测试网上运行 npx hardhat test --network local 或 npx hardhat test --network kovan 时出现未经授权的错误答案

【问题标题】：Unauthorized error when running npx hardhat test --network local or npx hardhat test --network kovan on Moralis forked testnet在 Moralis 分叉测试网上运行 npx hardhat test --network local 或 npx hardhat test --network kovan 时出现未经授权的错误

【问题描述】：

我正在尝试学习如何使用 Moralis 配置安全帽，我编写了一个智能合约，现在我想对其进行测试。我成功地分叉了一个 Moralis Kovan 网络和一个本地网络，我让它在我的计算机上运行。现在我想在 Moralis 的分叉 kovan 或本地网络上运行一些测试，但它们似乎都不起作用。

运行 npx hardhat test --network local 或 npx hardhat test --network kovan 时出现以下错误：HardhatError: HH110: Invalid JSON-RPC response received: {"error":"unauthorized"}

这是我的 hardhat.config.js

require("@nomiclabs/hardhat-waffle");
require("@nomiclabs/hardhat-etherscan");

const ethers = require('ethers');

task("accounts", "Prints the list of accounts", async (taskArgs, hre) => {
  const accounts = await hre.ethers.getSigners();

  for (const account of accounts) {
    console.log(account.address);
  }
});
