我尝试在多边形区块链上开发DApp。基本上我正在创建NFT，但几次之后我就遇到了这个错误。甚至当我不创建NFT时也会发生这个错误。这是我的代码。

const Web3 = require("web3")
const fs = require("fs")
var HDWalletProvider = require("@truffle/hdwallet-provider");
var provider = new HDWalletProvider(SECRET_PHRASE, "https://rpc-mumbai.maticvigil.com")
const web3 = new Web3(provider)
const constractJSON = JSON.parse(fs.readFileSync(`${process.cwd()}/contracts/Collection.json`))
const abi = constractJSON["abi"]
const byteCode = constractJSON["byteCode"]["object"]



const mintNFT = async (contractAddress,tokenURI,to) => {

    const contract = await new web3.eth.Contract(abi, contractAddress)    

    const result = await contract.methods.claimItem(tokenURI,to).send({from: WALLET_ADDRESS,gasLimit:6000000},)  
}

module.exports = mintNFT

下面是完整的错误。
