This is the section of my unit testing... I've been working on this problem for the last few hours. I couldn't, however... I think the error is in const { deployer } = await getNamedAccounts() this line. Raffle contract isn't recognized... (Note- All the deployments are working correctly... )

    !developmentChains.includes(network.name)
        ? describe.skip()
        : describe("Raffle UNIT test", async () => {
              let raffle, vrfCoordinatorV2Mock
              const chainId = network.config.chainId
              beforeEach(async () => {
                  const { deployer } = await getNamedAccounts()
                  await deployments.fixture(["all"])
                  raffle = await ethers.getContract("Raffle", deployer)
                  vrfCoordinatorV2Mock = await ethers.getContract("VRFCoordinatorV2Mock", deployer)
              })
              describe("Constructor function", async () => {
                  it("Initializes the raffle correctly.", async () => {
                      const raffleState = await raffle.getRaffleState()
                      const interval = await raffle.getInterval()
    
                      assert.equal(raffleState.toString(), "0")
                      assert.equal(interval.toString(), networkConfig[chainId]["interval"])
                  })
              })
          })

ERROR that I got...
