Documentextensions.SetStyle not working

Documentextensions.setstyle keeps throwing errors when I try to set the surface style as shown here:

Any idea why it does not work?

2

Can you check the outputs from the nodes upstream? They might return null as well.

Seems to be getting the surfaces in previous nodes,

What does the yellow errormessage say?

Warning: DocumentExtensions.SetStyle operation failed.
Could not load type ‘Autodesk.Civil.DatabaseServices.PressureAppurtenanceSectionLabel’ from assembly ‘AeccPressurePipesMgd, Version=13.3.854.0, Culture=neutral, PublicKeyToken=null’.

Not sure why but try to check the Style name and the last node.

The last node returned null after the first run because the surfaces didn’t had the style anymore that I Listed indices for on in the middle of the graph

I ended up modifying some python code to do the style change and seems to work. import sys
