Lesson 7 : ReferenceError: address is not defined

[arifulone]

I'm on Lesson 7: hardhat fundme, time: 10:52:00. here is 00-deploy-mocks.js:-

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

module.exports = async({getNamedAccounts,deployments})=>{
   const { deploy, log } = deployments
   const { deployer } = await getNamedAccounts()
   const chainId = network.config.chainId
   
   if(developmentChains.includes(network.name)){
       log("local network detected! deployed mocks..")
       await deploy("MockV3Aggregator",{
           contract:"MockV3Aggregator",
           from:deployer,
           log:true,
           args:[DECIMALS,INITIAL_ANSWER]
       })
       log("Mocks deployed !")
       log("_____________________________")
   }
}
module.exports.tags = ["all","mocks"]

01-deploy-mocks.js:-

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


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

    let ethUsdPriceFeedAddress 
    if(developmentChains.includes(network.name)){
        const ethUsdAggregator = await deployments.get("MocksV3Aggregator")
        ethUsdPriceFeedAddress = ethUsdAggregator.address
    }
    else{
        ethUsdPriceFeedAddress = networkConfig[chainId]["ethUsdPriceFeed"]
    }

    const fundMe = await deploy("FundMe",{
    from:deployer,
    args:[address],
    log:true,
    })
    log("____________________________")

}
 
module.exports.tags = ["all","fundme"]

helper-hardhat-config.js:-

 const networkConfig = {
    5:{
        name:"goerli",
        ethUsdPriceFeed:0x5f4eC3Df9cbd43714FE2740f5E3616155c5b8419,

    },
    137:{
        name :"polygon",
        ethUsdPriceFeed:0xF9680D99D6C9589e2a93a78A04A279e509205945,
    },
}

const developmentChains = ["hardhat","localhost"]
const DECIMALS = 8
const INITIAL_ANSWER = 200000000000


module.exports={
    networkConfig,
    developmentChains,
    DECIMALS,
    INITIAL_ANSWER
} 

after I run this command :
yarn hardhat deploy
gave this error :

yarn run v1.22.19

Hi,

you don't need "const chainId = network.config.chainId" line, since you using network.name to identify the network
