ID 587332 - A ZeroDivisionError occurs when changing the resolution of a sequence, which contains offline clips with a transformation soft effect applied

Problem summary
A ZeroDivisionError occurs when changing the resolution of a sequence, which contains offline clips with a transformation (Transform, Crop, ConerPin2D, etc.) soft effects applied.
 
Customer reported version
Nuke 15.1v3
 
Customer reported platform
Linux Rocky 8
 
Steps to reproduce
 
1) Open Nuke Studio.
 
2) Import (File > Import File(s)...) a clip and drop it on to the timeline.
 
3) Select the track item, open the Properties tab and change Clip Reformat to To Sequence Resolution.
 

 
4) Add a Transform soft effect to the track item (hotkey Alt+T).
 
5) Delete the track item's corresponding bin item. This will make your track item offline.
 
6) Open the Sequence tab and change Output Resolution to any other value.
 

 
7) Check the terminal for error messages.
 
Expected behaviour
Nuke should not error when reformatting a sequence, which contains offline clips with transformation soft effects applied.
 
Actual behaviour
A ZeroDivisionError occurs when reformatting the sequence:
