Invalid or missing response type

[salmanpatnee]

I'm following a tutorial in which a stand alone app is sending oauth request to WordPress, already OAuth2 server plugin installed and its give me Invalid or missing response type
Here is the JSO config:

var ROOTURL = "http://wp-rest.oo";
const RESTROOT = ROOTURL + '/wp-json';

var jso = new jso.JSO({
    providerID: "WP Editor",
    client_id: "PJmIzB9SGeLnseknJDzgXwKUWd9XujA2zocyCMwM",
    redirect_uri: "http://wpedit-oauth.oo/",
    authorization: ROOTURL + "/oauth/authorize",
});
// Catching the response when the user is returning
jso.callback();

This is the calling function:

function oauthLogin() {
	console.info('Login button pressed!');
	let opts = {
		redirect_uri: "http://wpedit-oauth.oo/"
	}
	jso.getToken(opts)
	.then((token) => {
		console.log("I got the token: ", token)
	})
	.catch((err) => {
		console.error("Error from passive loader", err)
	})
}

Client is already registered in WordPress. So what is the issue??
