Getting this error when trying to invoke these methods QueryVsanManagedStorageSpaceUsage, VsanQueryEntitySpaceUsage by using sample code from vsan 7.0u2 sdk java.

Code which invokes these Methods:

VsanhealthPortType healthPort; //initialised

VsanHealthConnection connection = (VsanHealthConnection) this.connection;

//QueryVsanManagedStorageSpaceUsage - not able to hit

QueryVsanManagedStorageSpaceUsageSpec queryVsanManagedStorageSpaceUsageSpec = new QueryVsanManagedStorageSpaceUsageSpec();

List<String> list1 = queryVsanManagedStorageSpaceUsageSpec.getDatastoreTypes();
list1.add(String.valueOf(VsanDatastoreType.PMEM));
list1.add(String.valueOf(VsanDatastoreType.VSAN));
list1.add(String.valueOf(VsanDatastoreType.VSAN_DATASTORE_TYPE_UNKNOWN));
list1.add(String.valueOf(VsanDatastoreType.VSANDIRECT));

try {
 
    Object obj3 = healthPort.queryVsanManagedStorageSpaceUsage(connection.getVsanSpaceReportServiceInstanceReference(),VsanUtil.ConvertToHealthMoRef(cluster),queryVsanManagedStorageSpaceUsageSpec);

  
}catch (Exception e){
    e.printStackTrace();
}



//VsanQueryEntitySpaceUsage - not able to hit

VsanSpaceQuerySpec vsanSpaceQuerySpec = new VsanSpaceQuerySpec();

vsanSpaceQuerySpec.setEntityType(String.valueOf(VsanSpaceReportingEntityType.HOST));

try {
     Object obj4 = healthPort.vsanQueryEntitySpaceUsage(connection.getVsanSpaceReportServiceInstanceReference(), VsanUtil.ConvertToHealthMoRef(cluster), vsanSpaceQuerySpec);
}catch(Exception e){
    e.printStackTrace();
}

I am not able to identify what is the cause of the error.The error is coming for both the function.Can anyone guide me what would be the cause of the error and if there is any way to get the error message which could make sense.
