Lesson9: Unit tests are failing

[Chizitere01]

In lesson 9 of the course, 5 out of the 14 unit tests are failing. The staging tests are working fine.
here are the errors I get

VM Exception while processing transaction: reverted with custom error 'InvalidConsumer()'

 Error: invalid arrayify value (argument="value", value={}, code=INVALID_ARGUMENT, version=bytes/5.7.0)

 Error: Timeout of 300000ms exceeded. For async tests and hooks, ensure "done()" is called; if returning a Promise, ensure it resolves. (/home/chizitere01/hh-fcc/hardhat-smartcontract-lottery-fcc/test/unit/Raffle.test.js)

1- To solve this issue

VM Exception while processing transaction: reverted with custom error 'InvalidConsumer()'

Add this condition to your 01-deploy-raffle.js code before verification condition.

 if (developmentChains.includes(network.name)) {
        const vrfCoordinatorV2Mock = await ethers.getContract("VRFCoordinatorV2Mock")
        await vrfCoordinatorV2Mock.addConsumer(subscriptionId, raffle.address)
    }

after this you going to run into new issue,

     AssertionError: Expected transaction to be reverted with reason 'Raffle__NotOpen', but it reverted with a custom error

to solve it by change revertedWith() to revertedWithCustomError
I don't know way sometimes works and sometimes doesn't.
2- To solve this issue

 Error: invalid arrayify value (argument="value", value={}, code=INVALID_ARGUMENT, version=bytes/5.7.0)

change {} to [] line 96

     const tx = await raffle.performUpkeep([])

3- You are going to run into new issue

     TypeError: Cannot read properties of undefined (reading 'toNumber')

change requestId to requestedId,
like this

    const requestId = txReceipt.events[1].args.requestedId

and add () to `toString()' line 111

    assert(raffleState.toString() == "1")

4- To solve this issue

 Error: Timeout of 300000ms exceeded. For async tests and hooks, ensure "done()" is called; if returning a Promise, ensure it resolves. (/home/chizitere01/hh-fcc/hardhat-smartcontract-lottery-fcc/test/unit/Raffle.test.js)

change {} to "0x" or [] line 185 like this

    const tx = await raffle.performUpkeep([])

and change requestId to requestedId line 189 like this

 await vrfCoordinatorV2Mock.fulfillRandomWords(
    txReceipt.events[1].args.requestedId,
    raffle.address
 ) 

output

  Raffle Unit Test
    constructor
      ✔ initializes the raffle correctly
    enterRaffle
      ✔ reverts when you don't pay enough
      ✔ records players when they enter
      ✔ emit event on enter
      ✔ doesn't allow entrance when raffle is calculating (79ms)
    checkUpkeep
      ✔ returns false if people haven't sent any ETH (43ms)
      ✔ returns false if raffle isn't open (73ms)
      ✔ returns false if enough time hasn't passed
      ✔ returns true if enough time has passed, has players, eth, and is open (45ms)
    performUpkeep
      ✔ it can only run if checkUpkeep is true (57ms)
      ✔ reverts when checkupkeep is false
      ✔ updates the raffle state, emits an event and calls the vrf coordinator (56ms)
    fulfillRandomWords
      ✔ can only be called after performupkeep (40ms)
Found the event!
