Error response in OSLC DM query

Hi,

I'm trying to execute Sample code from lyo.client > DMFormSample.java

I'm sure all of the argument values are correctly set and this class is able to Authenticate on JTS.

But this query response is

"

HTTP 400: Bad Request

_in predicate value array is empty
Caused by (IllegalArgumentException): _in predicate value array is empty

    

"

Code snapshot :

//STEP 3: Login in to Jazz Server
            if (client.login() == HttpStatus.SC_OK) {

                //STEP 4: Get the URL of the OSLC ChangeManagement catalog
                String catalogUrl = helper.getCatalogUrl();

                //STEP 5: Find the OSLC Service Provider for the project area we want to work with
                String serviceProviderUrl = client.lookupServiceProviderUrl(catalogUrl, projectArea);

                //STEP 6: Get the Query Capabilities URL so that we can run some OSLC queries
                String queryCapability = client.lookupQueryCapability(serviceProviderUrl,
                                                                      OSLCConstants.OSLC_AM_V2,
                                                                      OSLCConstants.AM_RESOURCE_TYPE);

                //SCENARIO A: Run a query for all AM Resources with OSLC paging of 10 items per
                //page turned on and list the members of the result

                OslcQueryParameters queryParams = new OslcQueryParameters();

                OslcQuery query = new OslcQuery(client, queryCapability, 10, queryParams);

                OslcQueryResult result = query.submit();

                processPagedQueryResults(result,client, processAsJavaObjects);

                System.out.println("\n------------------------------\n");

                //TODO:  Add more DM scenarios
            }

Any direction troubleshooting this further could be great help.

Thanks in Advance!

Warm Regards,

Jay
