Very strange, I ran your code on my machine and it deployed correctly. Does you constructor in your Raffle.sol read exactly the same as this?

constructor(
        address vrfCoordinatorV2, 
        uint256 entranceFee,
        bytes32 keyHash, 
        uint64 subscriptionId,
        uint32 callbackGasLimit,
        uint256 interval

etc...

Can you post your helper-hardhat-config.js?

[gmluqa]

Okay, found the issue, in your helper.hardhat.config.js in gasLane: " 0x" there is a space before the keyhash.

Your helper config should look like this instead:

const { ethers } = require("hardhat")

const networkConfig = {
    4: {
        name: "rinkeby",
        vrfCoordinator: "0x6168499c0cFfCaCD319c818142124B7A15E857ab",
        entranceFee: ethers.utils.parseEther("0.01"),
        gasLane: "0xd89b2bf150e3b9e13446986e571fb9cab24b13cea0a43ea20a6049a85cc807cc",
        subscriptionId: "0",
        callbackGasLimit: "500000",
        interval: "30",
    },
    31337: {
        name: "hardhat",
        entranceFee: ethers.utils.parseEther("0.01"),
        gasLane: "0xd89b2bf150e3b9e13446986e571fb9cab24b13cea0a43ea20a6049a85cc807cc",
        callbackGasLimit: "500000",
        interval: "30",
    },
}

const developmentChains = ["localhost", "hardhat"]

module.exports = {
    networkConfig,
    developmentChains,
}

Change your helper config to this, try deploy and it should work!

[PatrickAlphaC]

Great find :)

[kantoash]

thanks sir i figure it out it through analyzing your repo code

[Tosinkoa]

I'm unable to deploy mine too, importing VRF Mock into VRFCoordinatorV2Mock.sol throw some warning message.

I noticed when using "0x" as gasLane it will throw you another error: Error: incorrect data length (argument="gasLane", value="0x", code=INVALID_ARGUMENT, version=abi/5.5.0)

Only when I use the same gasLane as the one I defined for the rinkeby network it will work.

Just a thing to keep in mind or something to double check if it's not working :)
