Steps to reproduce:

After configuring VMware template for a VCenter Host, all the discoveries are working fine, direct VCenter items are working, VMware Guest data collection works fine but for all the Discovered ESXi all the discovered Items will go in Not Supported with the following message: 

Invalid URL: missing '/sdk'

The Host macro is correctly configured (in fact the discovery is working fine like vcenter and guest data collection).

Result:
Discovered hypervisor Items will go in Not Supported with this error:

Invalid URL: missing '/sdk'

So items like this are getting unsupported with error Invalid URL: missing '/sdk'
vmware.hv.datastore.read[\{$VMWARE.URL},\{$VMWARE.HV.UUID},68655505-3489cdc0-50ad-34800d2ebe58,rps]

While items like the following are working fine:
vmware.datastore.read[\{$VMWARE.URL},5ae9f76a-e8c453b0-f904-d06726cd0c32,rps]
vmware.vm.vfs.dev.read[\{$VMWARE.URL},\{$VMWARE.VM.UUID},scsi0:0,bps]

Expected:

Hypervisor items should work normally like others items discovered by the Template. **
