UnhandledPromiseRejectionWarning: Error: invalid json request [1.0.0-beta.47]

[imthatcarlos]

As was mentioned briefly in this comment, eth.getAccounts() fails with the latest release of web3 and truffle-hdwallet-provider

Expected behavior

Code didn't change, only updated packages, and eth.getAccounts() should return accounts

Actual behavior

Fails.

Steps to reproduce the behavior

const Web3 = require('web3');
const HDWalletProvider = require('truffle-hdwallet-provider');
let provider = new HDWalletProvider(process.env.MNEMONIC, infuraNodeURL(false, network));
let web3 = new Web3(provider);
const accounts = await web3.eth.getAccounts();
// see error below

I'm having the same issue with this.
Is there any work-around until beta.48 out?

@sydneyitguy I will release this fix today.
