1

Please provide the following:

  1. SDK Version: 3.13.1
  2. Platforms(Android/iOS/web/all): Android
      let redirectUrl = await AuthSession.getRedirectUrl(); //this will be something like https://auth.expo.io/@your-username/your-app-slug
      let result = await AuthSession.startAsync({
        authUrl:
          'https://accounts.spotify.com/authorize' +
          '?response_type=code' +
          '&client_id=' +
          credentials.clientId +
          (scopes ? '&scope=' + encodeURIComponent(scopes) : '') +
          '&redirect_uri=' +
          encodeURIComponent(redirectUrl),
      })
console.log(result);

gives me this error

The odd thing is that if I just open the link with Linking.openURL(), the flow is (seems?) correct. I can login and see the data that I want appended at the end of the URL, I just cannot get it from AuthSession.

I added a scheme, but it shouldn’t matter since I am just using an emulated app, right?
