Lesson 9: Error: invalid address or ENS name

[Holger-ap]

Hello.

Im getting an error from my 01-deploy-raffle.js script from lesson 9. When i try to deploy, it returns the error below, i've checked the addresses, but i can't seem to find a solution, anyone experienced this issues aswell, and any idea how to fix it?

My repository: here

The error:

Error: ERROR processing /home/holger/hardhat-smartcontract-lottery/deploy/01-deploy-raffle.js:
Error: invalid address or ENS name (argument="name", value={"type":"BigNumber","hex":"0x0de0b6b3a7640000"}, code=INVALID_ARGUMENT, version=contracts/5.7.0)

Thanks in advance.

@Holger-ap can you send a screenshot of the entire error message? Usually at the end it says on which line the error was caught or check that the addresses of the VRFCoordinatorV2 in the helper-hardhat-config are strings.

[pacelliv]

This might be quicker if you push the code to github and leave a link to it.

[Holger-ap]

Sure its here

[pacelliv]

@Holger-ap sorry for the wait.

In the IF-statement, you're calling the addConsumer method of the coordinator, which expect the address of the contract to add, you do not have that yet. What you want to do is to fund the subscription after creating one.

Change:

 await vrfCoordinatorV2Mock.addConsumer(subscriptionId, FUND_AMOUNT)

To:

 await vrfCoordinatorV2Mock.fundSubscription(subscriptionId, FUND_AMOUNT)

Also make sure to import ethers:

const { network, ethers } = require("hardhat")

Also, I spot a misspelled on the word accounts in the hardhat.config file for goerli. I think this could cause problems in the future.

This solved the problem! Thank you very much for your time and help!
