Optional "height" argument as keyword argument is invalid?

[chroteus]

This is OK:
visual_shape_id = pb.createVisualShape(pb.GEOM_CYLINDER, radius,[1,1,1],height,rgbaColor=[1,1,1,1], specularColor=[0.4,.4,0])

But this fails, saying "height" is not a valid keyword argument even though it's an optional argument.
visual_shape_id = pb.createVisualShape(pb.GEOM_CYLINDER, radius=0.5,height=0.5, rgbaColor=[1,1,1,1], specularColor=[0.4,.4,0])

The field is called length, docs need updating.

Ah, I see. Thank you.
