Lesson9: transcation keeps getting failed(Error: transaction failed)

[moayuisuda]

I have deployed my contract to goerli test network and configed VRF and Automation. but when I run my scripts to enter lottery, it keeps getting 'transaction failed'.

scripts/test.js:

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

const test = async () => {
  const deployer = (await getNamedAccounts()).deployer;
  const lottery = await ethers.getContract("Lottery", deployer);

  const tx = await lottery.enterLottery({
    value: ethers.utils.parseEther("0.01"),
  });
  console.log("entered");
  await tx.wait(1); // get failed here
  console.log("end");
};

test();

I tried ton of times, ethersan:

VRF:

Automation:

I have passed all my local unit test, but get trouble with goerli test network. Hope someone can help to see what is wrong.
