ProviderError：第一个参数无效：地址地址不是字符串

Question

我正在尝试在 goerli 网络上部署我的合约。下面是我的deployProxy.js

const { ethers, upgrades } = require("hardhat");

async function main() {
  const VendingMachineV1 = await ethers.getContractFactory("VendingMachineV1");
  const proxy = await upgrades.deployProxy(VendingMachineV1, [100]);
  await proxy.waitForDeployment();

  const implementationAddress = await upgrades.erc1967.getImplementationAddress(
    proxy.getAddress()
  );

  console.log("Proxy contract address: " + proxy.getAddress());

  console.log("Implementation contract address: " + implementationAddress);
}

main();

但是，部署合约后出现错误

const error = new ProviderError( ProviderError: invalid 1st argument: address address was not string

Answer 1

你应该添加“await”，因为它返回一个承诺。

这样：

const implementationAddress = await upgrades.erc1967.getImplementationAddress(
    await proxy.getAddress()
  );

  console.log("Proxy contract address: " + await proxy.getAddress());
