Lesson 9: Error Timeout of 200000ms exceeded (in the promise test)

[SimSimButDifferent]

Hi all I have been trying to debug this all morning.

So far I have tried increasing the timeout in hardhat.config (all the way to 900000). Checked for spelling mistakes and read through several github discussion posts with a similar title. If anybody could shed some light on this, I would really appreciate it.

I put the whole describe in below, the first "it" works fine.

        describe("fulfill random words", function () {
              beforeEach(async function () {
                  await lottery.enterLottery({ value: lotteryEntranceFee })
                  await network.provider.send("evm_increaseTime", [interval.toNumber() + 1])
                  await network.provider.send("evm_mine", [])
              })

              it("can only be called after performupkeep", async function () {
                  await expect(
                      vrfCoordinatorV2Mock.fulfillRandomWords(0, lottery.address)
                  ).to.be.revertedWith("nonexistent request")
                  await expect(
                      vrfCoordinatorV2Mock.fulfillRandomWords(1, lottery.address)
                  ).to.be.revertedWith("nonexistent request")
              })

              it("picks a winner, resets the lottery and sends money", async function () {
                  const additionalEntrants = 3
                  const startingAccountIndex = 1 // deployer = 0
                  const accounts = await ethers.getSigners()
                  for (
                      let i = startingAccountIndex;
                      i < startingAccountIndex + additionalEntrants;
                      i++
                  ) {
                      const accountConnectedLottery = lottery.connect(accounts[i])
                      await accountConnectedLottery.enterLottery({ value: lotteryEntranceFee })
                  }
                  const startingTimeStamp = await lottery.getLatestTimeStamp()

                  // performUpkeep (mock being chainlink keepers)
                  // fulfillRandomWords (mock being chainlink VRF)
                  // have to wait for fulfillRandomWords to be called
                  await new Promise(async (resolve, reject) => {
                      lottery.once("WinnerPicked", async () => {
                          console.log("Found the event!")
                          try {
                              const recentWinner = await lottery.getRecentWinner()
                              console.log(recentWinner)
                              console.log(accounts[2])
                              console.log(accounts[0])
                              console.log(accounts[1])
                              console.log(accounts[3])

                              const endingTimeStamp = await lottery.getLatestTimeStamp()
                              const numPlayers = await lottery.getNumberOfPlayers()
                              const winnerEndingBalance = await accounts[1].getBalance()

                              assert.equal(numPlayers.toString(), "0")
                              assert.equal(lotteryState.toString(), "0")
                              assert(endingTimeStamp > startingTime)

                              assert.equal(

                                          .mul(additionalEntrants)
                                          .add(lotteryEntranceFee)
                                          .toString()
