類型錯誤：getEnteranceFee 不是函式

我正在嘗試閱讀我的抽獎活動入場費，但我不斷收到此錯誤；

TypeError: getEnteranceFee is not a function

我知道有一個錯字，getEnteranceFee但它不應該影響任何事情，因為到處都是這樣。目前。

我已經嘗試過這裡給出的答案，但它對我不起作用。

我不明白為什麼useWeb3Contract無法獲得該功能。

RaffleEntrance.js 組件

import { useWeb3Contract, useMoralis } from "react-moralis"
import { abi, contractAddresses } from "../constants"
import { useEffect } from "react"

// have a funtion to enter the lottery

export default function RaffleEntrance() {
   const { chainId: chainIdHex, isWeb3Enabled } = useMoralis()
   const chainId = parseInt(chainIdHex)
   const raffleAddress = chainId in contractAddresses ? contractAddresses[chainId][0] : null
   /* const{runContractFuction: enterRaffle} = useWeb3Contract({
       abi: abi,
       contractAddress: raffleAddress, // specify networkId
       functionName: "enterRaffle",
       params: {},
       msgValue: 
   }) */

   const { runContractFuction: getEnteranceFee } = useWeb3Contract({
       abi: abi,
       contractAddress: raffleAddress, // specify networkId
       functionName: "getEnteranceFee",
       params: {},
   })

   useEffect(() => {
       if (isWeb3Enabled) {
           //try to read the raffle entrance fee
           async function updateUI() {
               const entranceFeeFromContract = await getEnteranceFee()
               console.log(entranceFeeFromContract)
           }
           updateUI()
       }
   }, [isWeb3Enabled])
   return <div>Hello from Lottery Entrance</div>
}

ABI 片段

您好，您在這一行中拼錯了 runContractFunction：

const { runContractFuction: getEnteranceFee } = useWeb3Contract({

它應該是：

const { runContractFunction: getEnteranceFee } = useWeb3Contract({

我建議重命名getEnteranceFee，這樣你就不會規范程式碼中存在的拼寫錯誤。
