Failed to Resolve a DID document

[m-yahya]

Description

I'm trying to resolve a DID document using did-resolver and ethr-did-resolver using the instructions described here:
https://github.com/uport-project/ethr-did-resolver#resolving-a-did-document

Sample Code

const Web3 = require('web3');
Web3.providers.HttpProvider.prototype.sendAsync = Web3.providers.HttpProvider.prototype.send
let provider = new Web3.providers.HttpProvider('http://localhost:9545')

const { Resolver } = require('did-resolver')
const { getResolver } = require('ethr-did-resolver')

const EthrDID = require('ethr-did');

let test = async () => {
    const registry = '0x71d2fb13e289fbb9ccae91571ca6637ccb29c727';
    const address = '0x23149630a1a84df75a8dccc3a50c02d0ad146d8e';

    const ethrDid = new EthrDID({ provider, registry, address });

    let did = ethrDid.did;

    const ethrDidResolver = getResolver(provider, registry)
    const didResolver = Resolver(ethrDidResolver)
    console.log(didResolver); // undefined

}

test();

Steps to Reproduce

1. init npm project
2. paste the above code into index.js
3. config the provider
4. replace the address and registry with your own stuff
5. install the web3, ethr-did, did-resolver, ethr-did-resolver dependencies
6. run node index.js

Expected Behaviour

It should resolve the DID Document for give DID.

Actual Behaviour

const didResolver = Resolver(ethrDidResolver) is undefined so the rest of code (didResolver.resolve('did:ethr:0x23149630a1a84df75a8dccc3a50c02d0ad146d8e').then(doc => console.log)) is not executing.

Versions

"did-resolver": "^1.0.0",
"ethjs-provider-http": "^0.1.6",
"ethr-did": "^1.1.0",
"ethr-did-resolver": "^1.0.1",

I think you are missing a new keyword

const didResolver = Resolver(ethrDidResolver)
// should be
const didResolver = new Resolver(ethrDidResolver)
