The flutter plugin is not able to set the user id.

Laravel route that returns the token :

public function beamsAuth(PusherAuthRequest $request)
    {
        try {
            $beamsClient = new PushNotifications([
                'instanceId' => env('PUSHER_BEAMS_INSTANCE_ID'),
                'secretKey' => env('PUSHER_BEAMS_KEY'),
            ]);
            $user = $request->user(); // If you use a different auth system, do your checks here
            $userID = $user['id'];
            $beamsToken = $beamsClient->generateToken("".$userID);
            $action = new CreateDeviceAction();
            $dto = DeviceDataTransferObject::fromArray([
                'os' => $request->input('os') ?? null,
                'timezone' => $request->input('timezone') ?? null,
                'token' => $beamsToken['token'] ?? null,
                'alfred_id' => $user['id'] ?? null,
            ]);
            $action($dto);
            return response()->json($beamsToken);
        } catch (\Exception $e) {
            throw new HttpResponseException(response()->json([
                'status' => false,
                'error' => $e->getMessage()
            ], 400));
        }
    }

Response from our server :

{
    "token": "eyJ0eXAiOiJKV1QiLCJhbGciO............."
}

if you got RangeError you need to catch it
` @OverRide
void handleCallback(String callbackId, String callbackName, List args) {
final callback = _callbacks[callbackId]!;

switch (callbackName) {
  case "onInterestChanges":
    callback((args[0] as List<Object?>).cast<String>());
    return;
  case "setUserId":
    try{
      callback(args[0] as String?);
    }on RangeError{
      callback("sucess");
    }

    return;
  case "onMessageReceivedInTheForeground":
    callback((args[0] as Map<Object?, Object?>));
    return;
  default:
    callback();
    return;
}

}`
because when success args is empty list

PusherBeams.instance.setUserId(...) works fine for me. Can you paste your client code here as well? The server's response looks correct.

[mmc-eastwolf]

This is the function that should create the token.

getSecure() async {
    final BeamsAuthProvider provider = BeamsAuthProvider()
      ..authUrl = 'https://<my-server>/secure'
      ..headers = {'Content-Type': 'application/json'}
      ..credentials = 'omit';

    await PusherBeams.instance.setUserId(
        'user-id',
        provider,
        (error) => {
              if (error != null) {print(error)}

              // Success! Do something...
            });
  }
