Why can’t I use the Spotify SDK in capacitor?

[royal1998]

I am using Ionic with Capacitor to build an app, which interacts with the Spotify APi.
Therefore I use the cordova-spotify-auth plugin and the capacitor-spotify plugin.

In the app, you are supposed to log in to Spotify and then the app is supposed to play a song on the device via the native Spotify mobile app.
The login via the cordova-spotify-auth plugin works, I also get an access token. However, using the Spotify SDK via capacitor-spotify plugin does not work. I get the following error messages:

2021-04-25 00:07:25.518 2445-2445/io.ionic.starter
E/Capacitor/Console: File: http://localhost/home-home-module.js - Line
1668 - Msg: Spotify SDK isn't supported on the web

2021-04-25 00:07:25.526 2445-2445/io.ionic.starter E/Capacitor/Console: File:
http://localhost/vendor.js - Line 59199 - Msg: ERROR Error: Uncaught
(in promise): Spotify SDK isn't supported on the web

This is my code:

cordova.plugins.spotifyAuth.authorize(config)
.then(({ accessToken, expiresAt }) => {
      this.result = { access_token: accessToken, expires_in: expiresAt};
      this.presentAlert(accessToken);
      SpotifySDK.connectToAppRemote();
      SpotifySDK.login();
      SpotifySDK.play({uri: 'spotify:track:4q6dqyGM25sKFU8nYAGRe4'});
});

Wouldn't Capacitor have to translate the code into native languages and thus make the Spotify SDK work?

Also, if you know any other way to play a song in the native Spotify mobile app via Capacitor or Cordova, please let me know.

It seems like you are importing the plugin incorrectly and thus not running the plugin's native code.
The error message comes from the web part (see here).

Please make sure that the plugin is imported like this:

import { Plugins } from '@capacitor/core';
import 'capacitor-spotify';
const { SpotifySDK } = Plugins;

Unfortunately that doesn't work either. I get the same error.
Is it possible that I have to use cordova instead of capacitor?
