LESSON 9: getting typeError when calling PerformUpkeep() in Raffle.test.js

[J-dev740]

error while passing empty bytes array to performUpkeep method
ErrorCode:

TypeError: invalid BytesLike value (argument="value", value="[]", code=INVALID_ARGUMENT, version=6.6.4)

bugged part of code:

            try {
                await raffle.performUpkeep([])
            } catch (error) {
                console.log(error)
                process.exit(1)
            }

complete Raffle.test.js code:

const {assert,expect}=require("chai")
const {getNamedAccounts,deployments,ethers,network}=require("hardhat")
const {networkConfig,developmentChains}=require("../../helper-hardhat-config")
const {time,helpers}=require("@nomicfoundation/hardhat-network-helpers")

hello @J-dev740 , you need to change this

- await raffle.performUpkeep([])
+ await raffle.performUpkeep("0x")

[ugur17]

Hi, can you explain why we should change this?

[Amrit-ko]

@Chevy3000 Sorry. I've missed your question) Now I don't remember exactly how did I found a solution) I was digging in code a lot and also searching for a similar problems at Stack Overflow

[Amrit-ko]

@ugur17 This is how you send BytesLike value in ethers v6

[YashGolani]

after adding the code as suggested by @J-dev740, am getting these error

1. Raffle
   Enter Raffle
   doesnt allow to enter when raffle is entering:

add below in beforeEach():

subscriptionId = await raffle.getSubId()
await vrfCoordinatorV2Mock.addConsumer(subscriptionId, await raffle.getAddress())

so that raffle is a valid consumer
