Lesson7: TypeError: Cannot destructure property 'deploy' of 'deployments' as it is undefined.

[Tang-hw]

Hi, I have got a error about this.

Here this my code:

const {
  networkConfig,
  developmentChains,
} = require("../helper-hardhat-config");

//hre is hardhat runtime environment
module.exports = async (getNamedAccounts, deployments) => {
  const { deploy, log } = deployments;
  const { deployer } = await getNamedAccounts();
  const chainId = network.config.getChainId;

  let ethUsdPriceFeedAddress;
  if (developmentChains.includes(network.name)) {
    const ethUsdAggregator = await deployments.get("MockV3Aggregator");
    ethUsdPriceFeedAddress = ethUsdAggregator.address;
  } else {
    ethUsdPriceFeedAddress = networkConfig[chainId]["ethUsdPriceFeed"];
  }
  log("----------------------------------------------------");
  log("Deploying FundMe and waiting for confirmations...");

  // how to make when we change links
  //when going for localhost or hardhat network we want to use a mock
  const fundMe = await deploy("FundMe", {
    from: deployer,
    args: [
      /*address*/
      ethUsdPriceFeedAddress,
    ], // put price feed address
    log: true,
  });
  log("-------------------------------------------------------");
};

module.exports.tag = ["all", "fundme"];

and here is the error:

Please help me, Thanks

I got it : I'm missing braces

before:

module.exports = async (getNamedAccounts, deployments) => {

replace

module.exports = async ({ getNamedAccounts, deployments }) => {
