Lesson 9: Error: Timeout of 40000ms exceeded. For async tests and hooks, ensure "done()" is called; if returning a Promise, ensure it resolves.

I am getting this error while stage testing

I checked on etherscan everything is working fine but on stage testing lottery.once is not catching "WinnerPicked" event in this line

I checked on etherscan my contract is emitting WinnerPicke event with winner address.
here is my contract address: 0x3E70bC501C08d8c62A60807135a806B6d27C1265

And my code: https://github.com/aman879/DecentralizedLotteryContract

[aman879]

I calculate time taken to catch WinnerPicked event in my etherscan and it exceeded 40000ms(40s) because of automation of 30s + 40-50s for generating request id which was greater than 40000ms.
So i increased the timeout for fulFillRandomWords to 120000ms(120s).
It worked.

Did the answer work for you ?
Also how much link did u fund the VRF with ?

[aman879]

Yeah, It did worked for me.
I didnt remember it but maybe 5-10 links.

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,
}
