Metamask 交易已確認但“內部 JSON RPC 錯誤”

我正在使用 getWeb3() 實例化契約並撥打電話，交易說已確認但當我打開開發人員工具時出現以下錯誤MetaMask - RPC Error: Internal JSON-RPC error.

我不確定我的程式碼有什麼問題..（主要來自 Truffle react-box）

import React, { Component } from "react";
import SimpleStorageContract from "./contracts/SimpleStorage.json";
import getWeb3 from "./utils/getWeb3";

import "./App.css";

class App extends Component {
 state = { storageValue: 0, web3: null, accounts: null, contract: null };

 componentDidMount = async () => {
   try {
     // Get network provider and web3 instance.
     const web3 = await getWeb3();
     // Use web3 to get the user's accounts.
     const accounts = await web3.eth.getAccounts();

     // Get the contract instance.
     const networkId = await web3.eth.net.getId();
     const deployedNetwork = SimpleStorageContract.networks[networkId];
     const instance = new web3.eth.Contract(
       SimpleStorageContract.abi,
       deployedNetwork && deployedNetwork.address,
     );

     // Set web3, accounts, and contract to the state, and then proceed with an
     // example of interacting with the contract's methods.
     this.setState({ web3, accounts, contract: instance }, this.runExample);
   } catch (error) {
     // Catch any errors for any of the above operations.
     alert(
       `Failed to load web3, accounts, or contract. Check console for details.`,
     );
     console.error(error);
   }
 };

 componentWillMount() {
   // Get network provider and web3 instance.
   // See utils/getWeb3 for more info.    
   getWeb3()
   .then(results => {
     this.setState({
       web3: results
     })

     // Instantiate contract once web3 provided.
     this.instantiateContract()

   .catch((error) => {

       // Stores a given value, 5 by default.
       return simpleStorageInstance.set(5, {from: accounts[0]})
     }).then((result) => {
       // Get the value from the contract to prove it worked.
       return simpleStorageInstance.get.call(accounts[0])

問題很可能是因為您正在執行本地測試網（Ganache，本地 geth for dev 或類似的）。並且您的 MetaMask 已連接到不同的測試網路，但您仍在使用相同的網路配置。（例如，您在執行中的 Ganache 實例中使用了相同的配置；然後您關閉了 Ganache 並稍後執行它）。

MetaMask 會被這個nonce數字弄糊塗。

但是，解決方案很簡單，您必須從 MetaMask 重置您的帳戶。來自https://metamask.zendesk.com/hc/en-us/articles/360015488891-Resetting-an-Account-New-UI-的步驟

1. 點擊右上角的圖示打開“我的賬戶”頁面，選擇“設置”
2. 在“設置”頁面，向下滾動找到“重置帳戶”。
3. 點擊“重置賬戶”

調試時我注意到消息：“eth-json-rpc-errors@2.0.2：包重命名：https://www.npmjs.com/package/eth-rpc-errors”

所以錯誤得到解決執行npm install --save eth-rpc-errors
