Couchbase lite Sync Warning

Mobile Couchbase Lite
1

I am new to couch base and I am using couchbaselite-1.4.0 for my JAVAFX application.

When I start the application, after few seconds, I am getting the below warning. And my database is not syncing with remote database anymore.

Dec 11, 2017 12:45:07 PM com.couchbase.lite.util.SystemLogger w
WARNING: Sync: Error converting lastSequence: null to long.  Using 0

My code is

Logger log = Logger.getLogger(DatabaseConfig.LOCAL_DATABASE);
log.setLevel(Level.ALL);
JavaContext context = new JavaContext();

Manager manager = null;
try {
    manager = new Manager(context, Manager.DEFAULT_OPTIONS);
} catch (IOException e) {
    e.printStackTrace();
}

try {
    if (manager != null) {
        database = manager.getDatabase(DatabaseConfig.LOCAL_DATABASE);

        // Create replicators to push & pull changes to & from Sync Gateway
        URL url = null;
        try {
            url = new URL(DatabaseConfig.REMOTE_DATABASE);
        } catch (MalformedURLException e) {
            e.printStackTrace();
        }

        initSync(url);

        //Initiating Views
        initViews();
    } else {
        Check.log(this,"initDatabase","manager is null");
    }
} catch (CouchbaseLiteException e) {
    e.printStackTrace();
}

}

private void initSync(URL url) {
List<String> pullChannels = Arrays.asList(ChannelType.ITEM, ChannelType.BILL,    ChannelType.CATEGORY, ChannelType.PURCHASE_BILL);
Check.temp("pullChannels: "+pullChannels);
if (url != null && pullChannels.size() > 0) {

    Authenticator authenticator = AuthenticatorFactory.createBasicAuthenticator(AppConfig.ADMIN_ID, AppConfig.ADMIN_PASSWORD);
    Check.temp("admin details: "+AppConfig.ADMIN_ID+" : "+AppConfig.ADMIN_PASSWORD);

    Replication push = database.createPushReplication(url);
    Replication pull = database.createPullReplication(url);

    pull.setChannels(pullChannels);

    push.setContinuous(true);
    pull.setContinuous(true);

    push.setAuthenticator(authenticator);
    pull.setAuthenticator(authenticator);

    push.start();
    pull.start();

    Check.temp("status: "+push.getStatus()+" x "+pull.getStatus());
} else {
    Check.log(this,"initSync","url or channels is null");
}
}

Please help me

@kanchikrishnateja,

The error message you observed could be a subsequent issue that is caused by the root cause.

It seems the code you posted is correct. From existing information, it is hard to diagnose the problem. Do you observe any other error message in the logcat? It could help to diagnose the problem further.
