Network Pool Object referenced by this attribute is not found

[vedrand]

Hello,

I am trying to get Network Pool as a variable in vRO 8.2.  Whatever network pool I pick (in the picture), it says  " Attribute 'var_0' missing object,

Object referenced by this attribute is not found".

Once I had success but do not remember which one I picked.

What can I do to more troubleshoot this? Is this the problem of VRO or vCloud Director.
