I faced Uncaught (in promise) DOMException error like below when I was developing Nuxt web app with Metamask(chrome) and truffle Ganache.

Uncaught (in promise) DOMException: Failed to execute 'postMessage' on 'Window': function (error, response) {
              if (!error) {
 ...<omitted>... } could not be cloned.

What I tried to do is send transactions to local blockchain(Ganache).

    async sendTransaction(obj) {
      const web3 = await getWeb3();
      // get account
      const accounts = await web3.eth.getAccounts();
      const roomFactory = await getRoomFactory();

      const result = await roomFactory.methods
        .send({ from: accounts[0] });
      console.log("result", result);

function getWeb3() and getRoomFactory() are following:

// getWeb()

const getWeb3 = () =>
  new Promise(async (resolve, reject) => {
    // Modern dapp browsers...
    if (window.ethereum) {
      const web3 = new Web3(window.ethereum);
      try {
        // Request account access if needed
        await window.ethereum.enable();
        // Acccounts now exposed
      } catch (error) {
    // Legacy dapp browsers...
    else if (window.web3) {
      try {
        // Use Mist/MetaMask's provider.
        const web3 = new Web3(window.web3.currentProvider);
        console.log("Injected web3 detected.");
      } catch (error) {
    // Fallback to localhost; use dev console port by default...
    else {
      try {
        const provider = new Web3.providers.HttpProvider(
        const web3 = new Web3(provider);
        console.log("No web3 instance injected, using Local web3.");
      } catch (error) {
import getWeb3 from "~/plugins/web3.js";
import RoomFactory from "./build/contracts/RoomFactory.json"; // which is build by truffle

const getRoomFactory = async () => {
  const web3 = await getWeb3();

  const abi = RoomFactory.abi;
  const networks = RoomFactory.networks["5781"];
  return web3.eth.Contract(abi, networks.address);

What I can do:

  • get accounts (web3.eth.getAccounts()) from metamask provider
  • get balance (web3.eth.getBalance(accounts[0]))

What I cannot do:

  • send transaction to other contracts (Mycontract.methods.myfunction().send())
  • call (Mycontract.methods.myfunction().call())



  • Web3: 1.0.0-beta.36
  • Metamask: 5.3.2
  • truffle: 5.0.1

Similar problem is on the issue of metamask-extension.

I'd appreciate it if you could help me with some tips. Thank you.


I solved this problem by installing 1.0.0-beta.37.
