Lesson 9 , cannot deploy raffle.sol

[0xtdey]

Every time I try to deploy this error below is shown - @alymurtazamemon
I have tried all the solutions and suggestions present in the discussions for similar issues but still, the error persists for me.

Error: ERROR processing /mnt/c/Users/91827/hardhat-lottery/deploy/01-deploy-raffle.js:
Error: missing argument:  in Contract constructor (count=5, expectedCount=6, code=MISSING_ARGUMENT, version=contracts/5.7.0)

Hello @tamoghna-dey

It is already telling you what is the issue. You are not passing enough arguments when deploying your raffle. You should carefully check and even console.log each argument for your raffle and see if you can find missing one as you are currently passing 5 and you need 6 arguments.

and also remember to replace every instance of arguments with args for everything to work as expected

I tried the solutions suggested still the same error persists :(

let me see your modified code

from the previous code I also see all your args are undefined so you can replace

 const entranceFee = networkConfig[chainId]
    const gasLane = networkConfig[chainId]
    const callbackGasLimit = networkConfig[chainId]
    const interval = networkConfig[chainId]

with this

 const entranceFee = networkConfig[chainId]["entranceFee"]
    const gasLane = networkConfig[chainId]["gasLane"]
    const callbackGasLimit = networkConfig[chainId]["callbackGasLimit"]
    const interval = networkConfig[chainId]["interval"]

And ensure they are what you have on your helper-hardhat-config

Here are the deploy scripts @Neftyr

module.exports = async ({ getNamedAccounts, deployments }) => {
    const { deploy, log } = deployments
    const { deployer } = await getNamedAccounts()
    const chainId = network.config.chainId
    // If we are on a local development network, we need to deploy mocks!
    if (chainId == 31337) {
