Unable to delete Network folder from Vmware Vsphere 6.5 vcenter

Hi,

I am currently using the latest vim25.jar java version (https://my.vmware.com/group/vmware/details?productId=614&downloadGroup=VS-AUTOMATIONSDK-JAVA65).

I have 6.5 Vcenter.  When I tried to delete the "Network folder" from that, this SDK is failed to find the path of the folder and eventually unable to delete the folder.

But the same SDK is working for other options(vm, hosts, datacenter folder types).

The specific Network type folders are not working.

Here is the code snippet I am using to delete the folders from vcenter.

_searchIndex = VimPortType.retrieveServiceContent.getSearchIndex();

ManagedObjectReference mor = VimPortType.findByInventoryPath(_searchIndex, inventoryPath); // this call unable to find the Network folder path

Can anyone please help us to resolve the issue

Thanks,

Satyababu
