(Resolved) PDG - ROP fetch error

[bdancer]

In the log I see error message "ERROR: Cannot find node 'None'", and hython process exiting right away and I'm pretty sure it's not related to V-Ray...

[update]: It seems "rop" is a reserved key-word used in PDG to setup ROP path internally, if I rename "rop" to smth else (e.g. "attr_rop") everything works fine:
