Getting this error while running mockOffchain.js"
TypeError: raffle.checkUpKeep is not a function at mockKeepers (/root/hardhat-fcc/hardhat-smartcontract-lottery-fcc/scripts/mockOffchain.js:6:43) at processTicksAndRejections (node:internal/process/task_queues:96:5) error Command failed with exit code 1.
Code inside the mockOffchain.js

const { ethers, network } = require("hardhat")

async function mockKeepers() {
    const raffle = await ethers.getContract("Raffle")
    const checkData = ethers.keccak256(ethers.toUtf8Bytes("0x"))
    const { upkeepNeeded } = await raffle.callStatic.checkUpKeep(checkData)
        
    if (upkeepNeeded) {
        const tx = await raffle.performUpkeep(checkData)
        
        const txReceipt = await tx.wait(1)
        const requestId = txReceipt.logs[1].args.requestId
        console.log(`Performed upkeep with RequestId: ${requestId}`)
        if (network.config.chainId == 31337) {
            await mockVrf(requestId, raffle)
        }
    } else {
        console.log("No upkeep needed!")
    }
}

async function mockVrf(requestId, raffle) {
    console.log("We on a local network? Ok let's pretend...")
    const vrfCoordinatorV2Mock = await ethers.getContract("VRFCoordinatorV2Mock")
    await vrfCoordinatorV2Mock.fulfillRandomWords(requestId, await raffle.getAddress())
    console.log("Responded!")
    const recentWinner = await raffle.getRecentWinner()
    console.log(`The winner is: ${recentWinner}`)
}

mockKeepers()
    .then(() => process.exit(0))
    .catch((error) => {
        console.error(error)
        process.exit(1)
    })

Before I was not getting the error but checkUpKeep was returning false but as of now it's not running at all

It's a typo K at here: const { upkeepNeeded } = await raffle.callStatic.checkUpKeep(checkData)

TYPO (Upper Case K): checkUpKeep ❌

FIX (Lower Case k): checkUpkeep ✅
