ID 596653 - Nuke script fails to render, due to nodes that are not connected the Write node

WARNING: CheckerBoard1: get(channels=0xf), but request() not called.

The issue appears to be related to the 3D nodes present in the script. 

Customer reported version
Nuke 15.1v5
 
Customer reported platform
N/A
 
Steps to reproduce
 
1) Open Nuke.
 
2) Open the attached script.
 
3) Execute the Write node, without using the frame server.
 
4) Open the Error Console and notice the following error:

WARNING: CheckerBoard1: get(channels=0xf), but request() not called.

 
Expected behaviour
The Nuke script should render. Nodes that are not actually connected to the Write node also shouldn't have any impact on the render either.
 
Actual behaviour
The Write node stops rendering and the following error is returned:

WARNING: CheckerBoard1: get(channels=0xf), but request() not called.

 
Workaround
In this case, deleting all of the nodes, other than the CheckerBoard and Write nodes, allows the script to be successfully rendered.
