I am creating my first Dapp by using web3 1.0.0-beta.37 and trufflfe

While getting the accounts in app.js by using ganache-CLI and Metamask, I am getting following error.

Uncaught TypeError: e is not a function in the console 

Following is my code of App.js

import React, { Component } from 'react';
import './App.css';
import FormSubmitContract from './contracts/FormSubmit.json';
import getWeb3 from './utils/getWeb3.js';

class App extends Component {
  state = {

 componentDidMount = async () =>{
    const web3 = await getWeb3();
    const accounts = await web3.eth.getAccounts();
    const networkId = await web3.eth.net.getId();
    const deployedNetwork = FormSubmitContract.networks[networkId];
    const  instance = new web3.eth.contract(FormSubmitContract.abi, 
    deployedNetwork, deployedNetwork.address);

I am able to print the web3 in console log

Proxy {_requestManager: s, currentProvider: MetamaskInpageProvider, eth: r, db: e.exports, shh: a, …}

But got undefined in

const accounts = await web3.eth.getAccounts();
console.log(accounts); ==> undefined

I think there has been change in web3 1+ versions for getting the accounts.

Help me. Thanks in advance

In Metamask, go to Setting -> Privacy & Security -> deactive the "Privacy Mode" option.

If you want to use the Privacy Mode then you have to modify your code



Couple of things to experiment with:

  1. Try using web3 1.0.0-beta.35
  2. Are you calling window.ethereum.enable() to unlock the selected user account?
   const { ethereum } = window
   if (ethereum) {
      try {
        const web3 = new Web3(ethereum)
        const selectedAccount = await ethereum.enable()
        if (!selectedAccount) {
          // User didn't give permission for dapp to access wallet
          console.log('User opted out')
        } else {
          // User allowed access
          console.log('user gave access!')
        return web3
      } catch (error) {
        // whoopsie!
  • What is it is not the ethereum and it's web3? if (window.web3) { const web3 = window.web3; console.log("Injected web3 detected."); resolve(web3); } Commented Jun 4, 2019 at 6:10
