Lesson 9: Error: Timeout of 40000ms exceeded

[parishill25]

Hi,
I got this error while trying to test my fulfilRandomWords function, i tried adding link to my vrf and keeper like they said in previous discussion but still got the same problem.

Error: Timeout of 40000ms exceeded. For async tests and hooks, ensure "done()" is called; if returning a Promise, ensure it resolves. (/root/lottery_1/test/unit/Raffle-test.js)

it ("pick a winner,resets the lottery,and sends money", async function () {
const addPlayer = 3
const indexPlayers = 1
const accounts = await ethers.getSigners()
for (let i = indexPlayers; i < indexPlayers + addPlayer; i++) {
    const connectAccount = raffle.connect(accounts[i])
    await connectAccount.enterRaffle({ value: raffleEntranceFee })
}
   const startingTimeStamp = await raffle.getLastTimeStamp()

     await new Promise(async (resolve, reject) => {
      raffle.once("Winner Picked", async () => {
        console.log("Found the event")
        try {
            const recentWinner = await raffle.getRecentWinner()
            console.log(recentWinner)

            const raffleState = await raffle.getRaffleState()
            const endingTimeStamp = await raffle.getLastTimeStamp()

            const numPlayers= await raffle.getNumberOfPlayers()
            assert.equal(numPlayers.toString(), "0")
            assert.equal(raffleState.toString(), "0")
            assert(endingTimeStamp > startingTimeStamp)
            
        } catch (e) {
            reject(e)
        }
        resolve()
    })

    const tx = await raffle.performUpkeep([])
    const txReceipt = await tx.wait(1)
    await vrfCoordinatorV2Mock.fulfillRandomWords(
        txReceipt.events[1].args.requestId,
        raffle.address
    )
})

@parishill25 On the chainlink's dashboard, below you will find the History for VRF and Upkeep, there you will find the failed requests tabs, if the request really triggered and gets failed then you will find the reason there.

[parishill25]

I didn't understand, VRF and Upkeep shows transactions but in the VRF there's any amount of chainlink consumed during testing.

[alymurtazamemon]

@parishill25 I said check the history of transactions and there you will find failed requests tab, there you will find the reason for failing the request.

I'm having the same issue. I tried to follow what @alymurtazamemon said, but I don't have any "failed requests tab". I only have the events tab.

[alymurtazamemon]

@mjviana As you can see Fulfillments are 0 which means your request is not triggered here. There could be many issues I have mentioned a discussion to look at, in your discussion, check it.

It worked for me when I put

mocha : {
    timeout : 200000,
}

in my hardhat.config

If that did not work you can try

mocha : {
    setTimeout : 200000,
}

It took me some time but I went step by step to fix it.
Finally, I saw it was an issue with the latest version of hardhat, ethers…
I am using the latest versions… "ethers": "^6.10.0», «hardhat": "^2.19.4", solidity ^0.8.19
The whole solution could be found at my repo: My Repo or directly at the raffle.staging.test.js @raffle.staging.test.js
Mainly changes in the latest versions… please note the main changes:

const raffleAddress = (await deployments.get("Raffle")).address
raffle = await ethers.getContractAt("Raffle", raffleAddress) //instead of getContract

setTimeout(resolve, 5000)                      
raffle.on("WinnerPicked", async () => { // instead of raffle.once

Hope this will help.
