lesson 9 (youTube streaming time around : 15:20) run into an error

[leung100]

when running "yarn hardhat deploy" in the terminal, got this error in the terminal:
Error: ERROR processing skip func of /home/leung/hh-fcc/hardhat-smartcontract-lottery-fcc/deploy/00-deploy-mocks.js:
Error: invalid decimal value (argument="value", value="0,01", code=INVALID_ARGUMENT, version=bignumber/5.6.2);

this my 00-deploy-mocks.js code:

`const { developmentsChains } = require("../helper-hardhat-config.js")
const { getNamedAccounts, deployments } = require("hardhat")

const BASE_FEE = ethers.utils.parseEther("0.25") //cost 0.25LINK token per VRF request
const GAS_PRICE_LINK = 1e9 // "1000000000" link per gas

module.exports = async function ({ getNamedAccounts, deployments }) {
    const { deploy, log } = deployments
    const { deployer } = await getNamedAccounts()
    const args = [BASE_FEE, GAS_PRICE_LINK]

    if (developmentsChains.includes(network.name)) {
        log("local network detected! deploying mocks......")
        //deploy a mock contract vrfcoordinator......
        await deploy("VRFCoordinatorV2Mock", { from: deployer, log: true, args: args })
        log("mocks deployed")
        log("-------------------------------------------------------------------------")
    }
}
module.exports.tags = ["all", "mocks"]

`
can someone please help me to solve this error? thanks you very much

[adityabhattad2021]

I guess you did a wrong import

const { getNamedAccounts, deployments } = require("hardhat")

This is the required import statement:

const { network } = require("hardhat")

[leung100]

change my code into:

`const { developmentsChains } = require("../helper-hardhat-config.js")
const { network } = require("hardhat")

const BASE_FEE = ethers.utils.parseEther("0.25") //cost 0.25LINK token per VRF request
const GAS_PRICE_LINK = 1e9 // "1000000000" link per gas

module.exports = async function ({ getNamedAccounts, deployments }) {
const { deploy, log } = deployments
const { deployer } = await getNamedAccounts()
const args = [BASE_FEE, GAS_PRICE_LINK]

if (developmentsChains.includes(network.name)) {
    log("local network detected! deploying mocks......")
    //deploy a mock contract vrfcoordinator......
    await deploy("VRFCoordinatorV2Mock", { from: deployer, log: true, args: args })
    log("mocks deployed")
    log("-------------------------------------------------------------------------")
}

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

still have the same errors

[leung100]

also tried out with this import, still the same error

const { developmentsChains } = require("../helper-hardhat-config.js")
const { network, ethers } = require("hardhat")

[adityabhattad2021]

There is no error in this deployment script, Please upload the code on github and share the repo.

[adityabhattad2021]

I assume that error comes from some typo, I guess "developmentsChains" check if you named that same in helper-hardhat-config.

[krakxn]

This should fix it:

const { developmentsChains } = require("../helper-hardhat-config.js")
-const { network } = require("hardhat")
+const { getNamedAccounts, deployments, network, ethers } = require("hardhat") // Remove for redundancy

[krakxn]

@adityabhattad2021 Yes, you are right. It does not make any difference though, and could remove it for redundancy.

[krakxn]

@leung100 Add: const { developmentsChains } = require("../helper-hardhat-config.js") -- BTW, is developmentsChains correct? Make sure there are no typos.

And, use this instead: const BASE_FEE = "250000000000000000"

Also, make sure whether your hardhat config has namedAccounts correctly.

[adityabhattad2021]

Yep, I even checked there is no error in this script, Problem has to be with developmentChain imported from helper-hardhat-config.

[leung100]

I fixed the error, the error was in helper-hardhat-config.js

-ethers.utils.parseEther("0,01")
+ethers.utils.parseEther("0.01" )

thank you very much for helping me out @krakxn @adityabhattad2021

[krakxn]

All the best!

@leung100 Hey can you give your helper-hardhat-config.js file for 9th lesson, please..

[leung100]

i am already at lesson 10, so the file has some adjustments, but it should be still for working for lesson 9
