Opennebula vOneCloud. Error: Undefined method `portgroup' for nil:NilClass

Question

Good afternoon, I’m just starting to learn cloud technologies, please help me with an error. I have esxi, vcenter and vOneCloud. Follow the instructions in this video: https://www.youtube.com/watch?v=AE2wklsg574

But, when i connect VM Network, i have 1 - VM Network - Port Group, and I’m catching error : Networks with ref network-12 could not be imported. undefined method `portgroup’ for nil:NilClass.

enter image description here

And then when importing I catch another error:

Template with ref vm-41 could not be imported. There was an error trying to create a virtual network to repesent a vCenter network for a VM or VM Template. Reason: undefined method `portgroup’ for nil:NilClass

Please help me figure it out.
