multi-unit controlnet is broken in the new version?

Thanks for your effort on this project.

I am using Controlnet 7a4805c8 version:v1.1.410 and automatic1111 v1.6.0

Here is how i am trying to use multi-units and the error i get.

class ControlNetUnit:
    '''
    This class was taken from the controlnet automatic1111 plugin since the unit that
    ships with webuiapi is not up to date and gives weird results for some models
