error when using addDelegate() function call as explained in the "Getting Started" documentation

[yogh333]

Describe the bug
I follow the "Getting Started" guide here: https://github.com/uport-project/ethr-did/blob/master/docs/guides/index.md, and try adding a Delegate Signer.

I am using Ganache for my own test private blockchain and deployed ERC1056 on it.

Here is my node.js code:

const EthrDID = require('ethr-did');              
const Web3 = require('web3');              
const Registry = require('./build/contracts/Registry.json');

const init = async () => {
	const current_provider = new Web3.providers.HttpProvider('http://localhost:8545');
	const web3 = new Web3(current_provider);
	const id = await web3.eth.net.getId();
	
	const deployedNetwork = Registry.networks[id];
	const contract = new web3.eth.Contract(
		Registry.abi,
		deployedNetwork.address
	);
	const addresses = await web3.eth.getAccounts();

	const ethrDid = new EthrDID({
		address: addresses[0], 
		registry: deployedNetwork.address, 
		privateKey: '0x2f93aa4f85edafb71f472bbd1be5046270aed1c6f6fcdd8fa0705c5ccb59ab12',
		rpcUrl: 'http://localhost:8545'
	});

	console.log("DiD = " + ethrDid.did);
	const owner = await ethrDid.lookupOwner();
	console.log("Owner = " + owner);

	console.log("Set Delegate = " + addresses[1]);
	await ethrDid.addDelegate(addresses[1]);
}

init();

Call to ethrDid.addDelegate() throws the following error:

(node:54879) UnhandledPromiseRejectionWarning: TypeError: Cannot read property 'delegateType' of undefined

This error originated either by throwing inside of an async function without a catch block, or by rejecting a promise which was not handled with .catch().

Any help would be welcome ;)
Thx,
Kind regards,
