I had the same issue. My problem was that I forgot to turn on the camera interface in the Interfacing Options with 'sudo raspi-config'

turn on the camera interface in the Interfacing Options with 'sudo raspi-config'

This should be in the readme

I have the same issue but turning on the camera doesn't work, maybe it is for debian 10 version of pi OS?
