android throws nullpointerexception at service.startForeground in production

I'm having this weird exception in production reported by Crashlytics in few users... I don't have really much information so i wasnt't able to reproduce it but i will paste everything crashlytics tells me

@SuppressLint("StringFormatMatches")
private void updateForegroundNotification(ServiceStatus status, Object extra) {

    Intent notificationIntent = new Intent(this, LoginActivity.class);
    PendingIntent pendingIntent = PendingIntent.getActivity(this, 0, notificationIntent, 0);

    String text = "sample";

    NotificationCompat.Builder mBuilder = new NotificationCompat.Builder(this, Constants.SERVICE_STATUS_NOTIFICATION_CHANNEL_ID)
            .setSmallIcon(R.drawable.ic_notification_logo)
            .setContentTitle(getString(R.string.foregroundNotification))
            .setContentText(text)
            .setPriority(NotificationCompat.PRIORITY_LOW)
            .setContentIntent(pendingIntent);

    startForeground(Constants.ID_FOREGROUND_NOTIFICATION, mBuilder.build());//line 656
}
