I’m trying to run a script with a python component to rotate an object using rhinoscriptsyntax.
While the original script runs fine, I get a NullReferenceException error when ran through Hops.
Is there a way to get this working?

rhinoscriptsyntax.RotateObjects is having an issue when running in an environment where no user interface exists due to this line
objs = rs.GetObjects("Select objects to rotate")
if objs:
point = rs.GetPoint("Center point of rotation")
if point:
rs.RotateObjects( objs, point, 45.0, None, True )
See Also:
RotateObject
"""
center_point = rhutil.coerce3dpoint(center_point, True)
if not axis:
axis = scriptcontext.doc.Views.ActiveView.ActiveViewport.ConstructionPlane().Normal
axis = rhutil.coerce3dvector(axis, True)
rotation_angle = Rhino.RhinoMath.ToRadians(rotation_angle)
xf = Rhino.Geometry.Transform.Rotation(rotation_angle, axis, center_point)
rc = TransformObjects(object_ids, xf, copy)
return rc
def ScaleObject(object_id, origin, scale, copy=False):
"""Scales a single object. Can be used to perform a uniform or non-uniform
scale transformation. Scaling is based on the active construction plane.
There are no views so the script is throwing an exception. We can fix this in rhinoscriptsyntax by always making axis equal to (0,0,1) but for now you could try passing the axis to your function. I added this to our bugtracker athttps://mcneel.myjetbrains.com/youtrack/issue/RH-69898

Ah! Many thanks!
This also helps for debugging other errors of the same sort.
