LESSON 09 : TypeError: Cannot read properties of undefined (reading 'JsonRpcProvider')

[Umairulislam]

Hello everyone,

I'm encountering an error while trying to deploy some mock contracts for my Hardhat smart contract project. Specifically, I'm getting the following error message:

Error: ERROR processing skip func of /home/ubuntu/folder/hardhat-smartcontract-lottery/deploy/00-deploy-mocks.js:

TypeError: Cannot read properties of undefined (reading 'JsonRpcProvider')

I'm not sure what's causing this error, and I would appreciate any help or insights that anyone might have. Here's the relevant code from my deployment/00-deploy-mocks.js script:

const { deployments, network, ethers } = require("hardhat")
const { developmentChains } = require("../helper-hardhat-config")
const BASE_FEE = ethers.utils.parseEther("0.25") // Cost 0.25 Link
const GAS_PRICE_LINK = 1e9 // Link per gas

module.exports = async function ({ getNamedAccounts, deployments }) {

    const { deploy, logs } = deployments
    const { deployer } = await getNamedAccounts()
    const chainId = network.config.chainId
    const args = [BASE_FEE, GAS_PRICE_LINK]

    if (developmentChains.includes(network.name)) {
        log("Local network detected! deploying mocks...")
        // deploy a mock contract
        await deploy("VRFCoordinatorV2Mock", {
            from: deployer,
            log: true,
            args: args
        })
        log("Mocks Deployed")
        log("---------------------------------------------")
    }
}

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

I'm not sure what's causing the TypeError that's being thrown. It seems to be related to the JsonRpcProvider, but I'm not sure how to fix it. Any help would be greatly appreciated!

Thank you!

The problem has been resolved I degraded my ethers version to 5.7.2
but now I get a different error in the same file

ReferenceError: log is not defined

Hi, I am getting an error expected 0 constructor arguments, got 6 while deploying 01-deploy-raffle.js.
I doubled check the constructor but nothing find there.

@Umairulislam Leave your repo link so I can see the code.

@Umairulislam Why you have abstracted your contract? Remove the abstract keyword from the contract.
