                          txReceipt.events[1].args.requestId,
                          raffle.address
                      )
                  })
              })

I think there is some problem in this part because while debugging my program was stopping here

await vrfCoordinatorV2Mock.fulfillRandomWords(
                          txReceipt.events[1].args.requestId,
                          raffle.address
                      )

Hey Nikhil

I've just quickly tested this, have a see if these work for you:

1. I don't think you need to convert your upkeepNeeded assert, try it without toNumber() so it looks like this: assert(!upkeepNeeded).

2. You don't appear to have wrapped the promise in the try catch, I've commented mine out to test and it does work so it's only a suggestion!

Let us know how you get on ...

Is this resolved, can this issue now be closed?
