Lesson 10: No contract deployed with name Raffle while running scripts

[harshuo2]

I have copied the mockOffChain.js code snippet from Patrick's github and when I deploy it, it runs perfectly. But when I try to run the scripts through, yarn hardhat run scripts/mockOffChain.js I shows me the following error:

Heyy!!
Error: No Contract deployed with name VRFCoordinatorV2Mock

The code snippet causing this error is:

async function mockKeepers() {
  console.log("Heyy!!")
  const raffle = await ethers.getContract("Raffle")

How do I mitigate this error?

@harshuo2 make sure the node is running on another terminal.

1. Make sure to have a local network running via node in a terminal
2. Do you have the following code in your script:

async function mockVrf(requestId, raffle) {
    console.log("We on a local network? Ok let's pretend...")
    const vrfCoordinatorV2Mock = await ethers.getContract("VRFCoordinatorV2Mock")
    await vrfCoordinatorV2Mock.fulfillRandomWords(requestId, raffle.address)
    console.log("Responded!")
    const recentWinner = await raffle.getRecentWinner()
    console.log(`The winner is: ${recentWinner}`)
}

3. If both of the above are true, try deploying all your contracts via deploy first, and then try running your script again.

Hope this helps!
