无法理解这个“无效BigNumber”错误是从哪里来的？

Question

我正在从事一项彩票dapp的工作，我在本地网络上部署我的合同时面临着一个问题。

我没有很大的经验调试这样的代码，我有点迷路了。

我可以从错误日志中清楚地看到，这个问题大约是一个很大的数值，但我无法理解代码中的问题在哪里，因为我无法从错误本身得到任何明确的解释。

有什么想法吗？

下面是部署的代码：

const { network, ethers } = require("hardhat")
const { developmentChains, networkConfig } = require("../helper-hardhat-config")
const { verify } = require("../utils/verify")

const VRF_SUB_FUND_AMOUNT = ethers.utils.parseEther("2")

module.exports = async function ({ getNamedAccounts, deployments }) {
    const { deploy, log } = deployments
    const { deployer } = await getNamedAccounts()
    const chainId = network.config.chainId
    let vrfCoordinatorV2Address, subscriptionId, vrfCoordinatorV2Mock

    if (developmentChains.includes(network.name)) {
        vrfCoordinatorV2Mock = await ethers.getContract("VRFCoordinatorV2Mock")
        vrfCoordinatorV2Address = vrfCoordinatorV2Mock.address
        const transactionRepsonse = await vrfCoordinatorV2Mock.createSubscription()
        const transactionReceipt = await transactionRepsonse.wait(1)
        subscriptionId = transactionReceipt.events[0].args.subId
        await vrfCoordinatorV2Mock.fundSubscription(subscriptionId, VRF_SUB_FUND_AMOUNT)
    } else {
        vrfCoordinatorV2Address = networkConfig[chainId]["vrfCoordinatorV2"]
        subscriptionId = networkConfig[chainId]["subscriptionId"]
    }

    const entranceFee = networkConfig[chainId]["entranceFee"]
    const gasLane = networkConfig[chainId]["gasLane"]
    const callbackGasLimit = networkConfig[chainId]["callbackGasLimit"]
    const keepersUpdateInterval = networkConfig[chainId]["keepersUpdateInterval"]

    const args = [
        vrfCoordinatorV2Address,
        entranceFee,
        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) && process.env.ETHERSCAN_API_KEY) {
        log("Verifying...")
        await verify(raffle.address, args)
    }
    log("----------------------------------------------------------------")
}

module.exports.tags = ["all", "raffle"]

Answer 1

上述错误是由于args数组中的参数定位错误造成的。

在创建deploy.js文件时，您应该遵循与创建raffle.sol文件相同的顺序。
