While deploying contract using mocks getting this error "Cannot read properties of undefined (reading 'length')"

[Nikhil8400]

i have used await with get named accounts

[Nikhil8400]

//This is my deploy-mocks file

const {network, deployments} = require("hardhat") const {developmentChains, DECIMALS, INITIAL_ANSWER} = require("../helper-hardhat-config.js")

module.exports = async ({ getNamedAccounts, deployment})=>{ const {deploy, log} = deployments const{deployer} = await getNamedAccounts() const chainId = network.config.chainId

if(chainId == 31337){
    log("Local network detected! Deploying mocks....")
    await deploy("MockV3Aggregator", {
        contract:"MockV3Aggregator",
        from: deployer,
        log:true,
        args:[DECIMALS,INITIAL_ANSWER]        //we have to pass constructor parameter for mockV3Aggregator
        //decimal parameter is going to equal to this decimal function...  and the _initial answer parameter tells with what does price feed starting with
        //Decimal should be placed 1st then place initial_answer accoding the constructor for MockV3Aggregator we can go and check in node modules files 
    })
    log("Mocks deployed!")
    log("___________________________________________________")
}

}

module.exports.tags = ["all","mocks"]

Try using this code. You will need to create a development chains array in your heper-hardhat-config with ["hardhat","localhost"] for the if statement

//Contract that we can use to deploy a fake price feed to a blockchain
const { network } = require("hardhat")
const { networkConfig } = require("../helper-hardhat-config")
const {
    developmentChains,
    DECIMALS,
    INITIAL_ANSWER,
} = require("../helper-hardhat-config")

module.exports = async ({ getNamedAccounts, deployments }) => {
    const { deploy, log } = deployments
    const { deployer } = await getNamedAccounts()

    if (developmentChains.includes(network.name)) {
        log("Local network detected! Deploying mocks...")
        await deploy("MockV3Aggregator", {
            contract: "MockV3Aggregator",
            from: deployer,
            log: true, //is deploying, what transaction is doing and where it is deployed with how much gas
            args: [DECIMALS, INITIAL_ANSWER],
        })
        log("Mocks deployed")
        log("-----------------------------------------------------------")
    }

    //We don't want to deploy this mock contract to a test net that actually has price feed
}

module.exports.tags = ["all", "mocks"]
