Describe the bug

const { assert, expect } = require("chai")

const { network, deployments, ethers, getNamedAccounts } = require("hardhat") const { developmentChains, networkConfig } = require("../../helper-hardhat-config")

!developmentChains.includes(network.name) ? describe.skip : describe("Raffle Unit Tests", function () { let raffle, VRFCoordinatorV2Mock, raffleEntranceFee, deployer const chainId = network.config.chainId beforeEach(async function () { deployer = (await getNamedAccounts()).deployer await deployments.fixture(["all"]) raffle = await ethers.getContract("Raffle", deployer) VRFCoordinatorV2Mock = await ethers.getContract("VRFCoordinatorV2Mock", deployer) raffleEntranceFee = await raffle.getEntranceFee() })

      describe("constuctor", async function () {
          it("initializes the raffle correctly", async function () {
              const raffleState = await raffle.getRaffleState()
              const interval = await raffle.getInterval()
              assert.equal(raffleState.toString(), "0")
              assert.equal(interval.toString(), networkConfig[chainId]["interval"])
          })
      })
      describe("enterRaffle", async function () {
          it("reverts when you don't pay enough", async function () {
              await expect(raffle.enterRaffle()).to.be.revertedWith(
                  "Raffle_NotEnoughETHEntered",
              )
          })

          it("Record when players enter", async function () {
              await raffle.enterRaffle({ value: raffleEntranceFee })
              const playerFromContract = await raffle.getPlayer(0)
              assert.equal(playerFromContract, deployer)
          })

          it("emits an event on enter", async function () {
              await expect(raffle.enterRaffle({ value: raffleEntranceFee })).to.emit(
                  raffle,
                  "raffleEnter",
              )
          })
      })
  })

I am getting TypeError: Cannot read properties of undefined (reading 'waitForTransaction') when emitting my event.Can anyone fix this?
