I didn't run into this issue before; I'm trying to solve this error. |

to solve this, in const { network, ethers } = require("hardhat")
const { developmentChains, networkConfig } = require("../helper-hardhat-config")
const { verify } = require("../utils/verify")
const VRF_SUB_FUND_AMOUNT = ethers.parseEther("1") // 1 Ether, or 1e18 (10^18) Wei
module.exports = async function ({ getNamedAccounts, deployments }) {
const { deploy, log } = deployments
const { deployer } = await getNamedAccounts()
const chainId = network.config.chainId
let vrfCoordinatorV2Address, subscriptionId
if (chainId == 31337) {
const vrfCoordinatorV2Mock = await ethers.getContract("VRFCoordinatorV2Mock")
vrfCoordinatorV2Address = vrfCoordinatorV2Mock.target
const transactionResponse = await vrfCoordinatorV2Mock.createSubscription()
const transactionReceipt = await transactionResponse.wait(1)
subscriptionId = 1
// Fund the subscription
await vrfCoordinatorV2Mock.fundSubscription(subscriptionId, VRF_SUB_FUND_AMOUNT)
} else {
// testnet
vrfCoordinatorV2Address = networkConfig[chainId]["vrfCoordinatorV2"]
subscriptionId = networkConfig[chainId]["subscriptionId"]
}
const raffleEntranceFee = networkConfig[chainId]["raffleEntranceFee"]
const gasLane = networkConfig[chainId]["gasLane"]
const callbackGasLimit = networkConfig[chainId]["callbackGasLimit"]
const keepersUpdateInterval = networkConfig[chainId]["keepersUpdateInterval"]
const args = [
vrfCoordinatorV2Address,
raffleEntranceFee,
gasLane,
subscriptionId,
callbackGasLimit,
keepersUpdateInterval,
]
const raffle = await deploy("Raffle", {
from: deployer,
args: args,
log: true,
waitConfirmations: network.config.blockConfirmations || 1,
})
if (developmentChains.includes(network.name)) {
const vrfCoordinatorV2Mock = await ethers.getContract("VRFCoordinatorV2Mock")
await vrfCoordinatorV2Mock.addConsumer(subscriptionId, raffle.address)
}
if (!developmentChains.includes(network.name) && process.env.ETHERSCAN_API_KEY) {
log("Verifying...")
await verify(raffle.address, args)
}
log("Raffle Deployed!")
log("------------------------------")
}
module.exports.tags = ["all", "raffle"] |

test script
it("doest allow entrance when raffle is calculating", async function () {
...
await raffle.performUpkeep("0x")
...
it("returns false if raffle isnt open", async function () {
...
await raffle.performUpkeep("0x")
...
it("returns false if enough time hasn't passed", async function () {
...
await network.provider.send("evm_increaseTime", [
Number(keepersUpdateInterval) - 5,
])
...
it("updates the raffle state, emits an event, and calls the vrf coordinator", async function () {
const txResponse = await raffle.performUpkeep("0x")
...
const raffleState = await raffle.getRaffleState()
...
it("picks a winner, resets, and sends money", async () => {
...
startingBalance = await ethers.accounts[2].getBalance()
...still some issues not solved |
