          await raffle.enterRaffle({ value: raffleEntranceFee })
          await network.provider.send("evm_increaseTime", [interval.toNumber() + 1])
          await network.provider.send({ method: "evm_mine", params: [] })
          await raffle.performUpkeep([]) 
          await expect(raffle.enterRaffle({ value: raffleEntranceFee })).to.be.revertedWith(

@maadi7 Push the code to repo and leave a link here I will check the issue.

[maadi7]

yeah sure!!

link :- https://github.com/maadi7/hardhat-lottery

thanks for the help :)

[alymurtazamemon]

@maadi7 Ok, will notify you.

[krakxn]

Could you push to a repo and link it here, thanks

[maadi7]

yeah sure!!

thanks for the help!!!

I have not looked at your repo yet, but is your subscription sufficiently funded w LINK and some test ETH?

[maadi7]

do you mean my wallet? yes, it is.
is subscription is same?

[krakxn]

The subscription (Chainlink VRF), not the wallet

[adityabhattad2021]

The order of arguments is incorrect in accordance to constructor in your raffle.sol :

const args = [vrfCoordinatorV2Address ,entranceFee, gasLane, subscriptionId, callbackGasLimit, interval]

In 01-deploy-raffle.js try this instead:

const args=[
    vrfCoordinatorV2Address,
    subscriptionId,
    gasLane,
    entranceFee,
    callbackGasLimit,
    interval
]

[maadi7]

Thank you so much...................
it worked.
this error almost took my whole day but finally it's resolves just because of you
once again thank you so much!!!!!
