tried to copy paste the same code stil stuck in the error can anyone please say whats going on here ?? looks like something wrong around subscriptionId

@sadath-12 Leave your repo link.

[sadath-12]

  if (!developmentChains.includes(network.name)) {
        await vrfCoordinatorV2Mock.addConsumer(subscriptionId.toNumber(), raffle.address)
    }

here we are adding subscription to mock when we are not in developement chains ?? quite confused with this

[alymurtazamemon]

@sadath-12 I am not sure who has added this to the repo but this was not included in the initial code.

[sadath-12]

yeah i c it was not included in the video

[alymurtazamemon]

@sadath-12 Should we mark it?

[sadath-12]

yes its solved thanks

[SidharthK2]

Try

1. yarn hardhat clean
2. yarn hardhat compile
   then run your tests and lmk

[sadath-12]
