NO2.11011: error while submitting changes to remote collection

[shadialian]

I am trying to use nitrite database with a project I am working on and it needs to be connected to the datagate server.

I set up the users and clients when syncing starts it throwing this error.
on the client side
org.dizitart.no2.exceptions.SyncException: NO2.11011: error while submitting changes to remote collection

on the server side
org.dizitart.no2.exceptions.InvalidOperationException: NO2.3009: document id is an auto generated value and can not be 771985705443479845

and I have a question. do I need to create the collection manually on mongo.

Thanks for help

I strongly suggest you consider the reference documentation first - http://www.dizitart.org/nitrite-database/doc/2.0.0/index.html#replication

You don't need to manually create the collections in mongo. It will be created by this line from client

DataGateSyncTemplate syncTemplate
        = new DataGateSyncTemplate(dataGateClient, "remote-collection@userId");

Here "remote-collection@userId" is the collection name that will be created in mongo by datagate.

I've been throw the documentation many times but nothing.

this is my client code.

DataGateClient dataGateClient = new DataGateClient("http://localhost:9090")
        .withAuth("shadi", "123456")
        .withUserAgent(userAgent);
DataGateSyncTemplate syncTemplate
        = new DataGateSyncTemplate(dataGateClient, "test-collection@shadi");
NitriteCollection collection = DB.getCollection("test");      
SyncHandle syncHandle = Replicator.of(DB)
        .forLocal(collection)
        // a DataGate sync template implementation
        .withSyncTemplate(syncTemplate)
        // replication attempt delay of 1 sec
        .delay(timeSpan(1, TimeUnit.SECONDS))
        // both-way replication
        .ofType(ReplicationType.BOTH_WAY)
        // sync event listener
        .withListener(new SyncEventListener() {
            @Override
            public void onSyncEvent(SyncEventData eventInfo) {
              System.out.println("data is synced" + eventInfo.getError());
            }
        })
        .configure();
syncHandle.startSync();
Document doc = createDocument("firstName", "John")
     .put("lastName", "Doe")
     .put("birthDay", new Date())
     //.put("data", new byte[] {1, 2, 3})
     //.put("fruits", new ArrayList<String>() {{ add("apple"); add("orange"); }})
     .put("note", "a quick brown fox jump over the lazy dog");
collection.insert(doc);
DB.commit();
DB.close();

my client application is throwing this exception

please if you any idea where would look for a solution

[anidotnet]

I'll take a look into it tomorrow. Meantime can you also go through one of the datagate junit tests? That might give you an idea if you are doing anything wrong. Now is the night time for me here, so can't be of immediate help. This is the file you need to look at - https://github.com/dizitart/nitrite-database/blob/master/nitrite-datagate/src/test/java/org/dizitart/no2/datagate/DataGateSyncTest.java

[anidotnet]

Sorry for the late reply, I was so caught up with my work.

Can you please remove the line - DB.close() from your code and test? The close() call will shutdown the sync thread and can cause unexpected result. Meantime, please look into the this test file - SyncIntegrationTest.java for properly initializing your sync code. And let me know if you still see any issue.
