What needs to be changed in gulpfile.js to give a tunnel (i.e. a link to open on another device)?

Question

Node.js

Hello.
I wrote server settings in gulpfile.js:
var config = {
server: {
baseDir: "./dist"
},
tunnel: true,
host: 'localhost',
port: 8080,
logPrefix: "MAX"
};
I run the gulp command and the error is:
$ gulp

But when I remove everything from the server settings, except:
var config = {
server: {
baseDir: "./dist"
}
};
and I delete everything from dist, then the browser opens. But there is no link (Tunnel) in the console, but I need it.
