wifi.setHostname, or setIp on Espy WIFI

Okay Gordon, I'm really not getting it. Here is the Github for what we got goin:

https://github.com/giokincade/autolocato­rjs.git

The current file I am deploying is mw-test.js. The relevant code is:

const connectToWifi = () => {
	wifi.connect(WIFI_NAME, WIFI_OPTIONS, (err)  => {
		if (err) {
		  console.log("Connection error: " + err);
		  return;
		} else {
			console.log("Wifi Connected!");
			
			var info = {
				ip: "192.168.1.9"
			};
			
			wifi.setIP(info, wifi.getIP((err) => {
				console.log("IP set!");
				startServer();
			}));
		}
	});
};

I checked that it's syntactically valid, etc.-- seems fine. But the Espy is throwing an error w underlying code, I believe. And it is looping the upload process. Here's one cycle. Also, I'm including my deploy process as well. I'm a newbie so some basic mistake is totally possible.

What am I doing wrong here? For what it's worth, our initial test.js works:

>Upload Complete
Wifi Connected!
IP Address: 192.168.1.158
Starting Server
Processing request
Processing request

The setIP part of this is causing the failure. I don't get it. Any ideas?
