react-native-app-auth: Failed to fetch configuration

Hi! I’m trying to make uber oauth2 work but I keep getting this error (currently testing on android).

Error: Failed to fetch configuration

From what I’ve seen in issues, this is a problem with ‘issuer’ variable. Seems like I can’t understand what string I should use there.

Here is my code

    const scopes = ["request"];
    const appAuth = new AppAuth({
      issuer: "https://login.uber.com/oauth/v2/authorize",
      clientId: settings.UberClientId,
      redirectUrl: "myApp:/oauth"
    })

    appAuth.authorize(scopes).then((response)=>{
      console.log('response=>', response)
    }).catch((reject)=>{
      console.log('reject=>', reject)
    });
