Capture vApp to template via API

Hi,

I want to create template from vApp and also as parameter include vdc compute policy. Main goal is separate win OS on selected hosts.

Successfully created  template via API without "CaptureVmParams" elements, but when I add these parameters call fails with 500 error code.

VM link I think is correct because I can browse VM parameters using this link also VDC policy is in place. What I'm missing?
