Problem on Raffle unit test (entrance calculation test)

[Sosiaalinen]

I get an error

1) Raffle Unit tests
       enterRaffle
         doesn't allow entrance when raffle is calculating:
     Error: VM Exception while processing transaction: reverted with custom error 'InvalidConsumer()'

I've been trying to fix it, but nothing seems to work. Here is my test. everything seems to work up until "doesn't allow entrance when raffle is calculating".

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

!developmentChains.includes(network.name)
    ? describe.skip
    : describe("Raffle Unit tests", async function () {
          let raffle, VRFCoordinatorV2Mock, entranceFee, deployer, interval
          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)
              entranceFee = await raffle.getEntranceFee()
              interval = await raffle.getInterval()
          })

          describe("constructor", 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 if you don't pay enough", async function () {
                  await expect(raffle.enterRaffle()).to.be.revertedWith("Raffle__NotEnoughETH")
              })
              it("keeps record of entering players", async function () {
                  await raffle.enterRaffle({ value: entranceFee })
                  const playerFromContract = await raffle.getPlayer(0)
                  assert.equal(playerFromContract, deployer)
              })
              it("emits event on enter", async function () {
                  await expect(raffle.enterRaffle({ value: entranceFee })).to.emit(
                      raffle,
                      "RaffleEnter"
                  )
              })
              it("doesn't allow entrance when raffle is calculating", async function () {
                  await raffle.enterRaffle({ value: entranceFee })
                  await network.provider.send("evm_increaseTime", [interval.toNumber() + 1])
                  await network.provider.send("evm_mine", [])
                  // Pretend to be a Chainlink Keeper -- empty call data === []
                  await raffle.performUpkeep([])
                  await expect(raffle.enterRaffle({ value: entranceFee })).to.be.revertedWith(
                      "Raffle__NotOpen"
                  )
              })
          })
      })

Hi @Sosiaalinen ,
It is normal, I believe the video is not up to date in that regard. You need to programmatically add a consumer in your raffle deploy script. It should look something like this (I named the contract Lottery instead of Raffle) :

Thank you! Got it solved by using your answer
