Lesson 9 : (TypeError: vrfCoordinatorV2Mock.createSubscription is not a function)

[MahzyarSaadat]

hello there,
When i use the "ethers" to get the "Mock contract" ,this error occurs:

(0 , ethers_1.getaddress) is not a function

And when i try to get the "mock" by using "deployments" , i see this error:

TypeError: vrfCoordinatorV2Mock.createSubscription is not a function

Also , I tied to use the compatible packages , because "hardhat-deploy" package has lots of problem with "ethers@^6"
It's a really comfusing situation ....

In your file 01-Raffle-deploy.js, change the 15th line (as of your code on github repo)

const vrfCoordinatorV2Mock = await ethers.getContract("VRFCoordinatorV2Mock", deployer)

[shikhar229169]

Also, after deploying the Raffle contract, you need to add one more line:

if (deploymentChains.includes(network.name)) {
    await vrfCoordinatorV2Mock.addConsumer(subscriptionId, raffle.address)
}

First of all
you must not include .env file in your repo, so do not use that account for real money.

package.json
replace this line

    "@nomiclabs/hardhat-ethers": "npm:hardhat-deploy-ethers",

with this

    "@nomiclabs/hardhat-ethers": "npm:hardhat-deploy-ethers@^0.3.0-beta.13",

use npm i --force to install package.
and as @shikhar229169 said, change deployments.get to ethers.getContract
like this

const vrfCoordinatorV2Mock = await ethers.getContract("VRFCoordinatorV2Mock", deployer)

I hope it help.
