HTTPException On refreshToken

[thenhawke]

I keep getting this exception _TypeError (type '(HttpException) => Null' is not a subtype of type '(dynamic) => dynamic') when I call auth0.auth.refreshToken.

My code to call it is like this:

try {
  var response = await auth0.auth.refreshToken({
    'refreshToken': refreshToken,
  });
  return response;
} catch (e) {
  print("Unable to refresh: ${e.toString()}");
}

The exception is being raised by the await auth0.auth.refreshToken line and isn't being caught by the try ... catch block, it is paused by VSCode. Am I doing something wrong, or is there a bug in the underlying library? Happens on a physical phone and on the emulator.

same issue here, but in my case it happen on authorize

final response = await _auth.webAuth.authorize({
  'audience': 'https://${_auth.auth.client.domain}/userinfo',
  'scope': _config.auth0Scopes,
});

@thenhawke , you need to do two things:

1. Go into auth0 > APIs > Click on your custom API > Access Settings > Allow Offline Access
2. Do something like this:

  void _refreshToken() async {
    try {
      var response = await auth.auth.passwordRealm({
        'username': uctrl.text,
        'password': pctrl.text,
        'realm': 'Username-Password-Authentication',
        'scope': 'offline_access'
      });
      Auth0Auth authClient = Auth0Auth(
          auth.auth.clientId, auth.auth.client.baseUrl,
          bearer: response['access_token']);
      var info = await authClient.refreshToken({
        'refreshToken': '${response['refresh_token']}',
      });
      showInfo('Refresh Token', '''
        \ntoken_type: ${info['token_type']}
        \naccesstoken: ${info['access_token']}
        ''');
    } catch (e) {
      print(e);
    }
  }
