Await errors on fresh install

[kevintayloruk]

I'm probably doing something fundamentally wrong but the example code appears to throw await promise errors as documented below. All advice welcomed.

Steps to reproduce:

Install npm package:
npm i node-emberplus

Create file from example code:

const {EmberClient, EmberClientEvent, LoggingService} = require('node-emberplus');
const client = new EmberClient({host: '192.168.1.2', port: 9000, logger: new LoggingService(5)});
client.on(EmberClientEvent.ERROR, e => {
   console.log(e);
});

await client.connectAsync();
// Get Root info
await client.getDirectoryAsync();
// Get a Specific Node
let node: TreeNode = await client.getElementByPathAsync("0.0.2");
console.log(node);
// Get a node by its path identifiers
node = await client.getElementByPathAsync("path/to/node");
console.log(node);
// Expand entire tree
try {
   await client.expandAsync();
}catch(e) {
   console.log(e.stack);
};

Run:

[user-hidden]% node index.js
[full-path-hidden]/lawo-node-ember-plus/index.js:7
await client.connectAsync();
^^^^^
