[ERR][ALL][00:motionplus] mlp_init_cam_start: Unable to open camera

[Tobus]

Hello,
I am using a Raspberry PI Zero 2W and the camera v2 on bookwork OS. I deployed the Motionplus docker container (crcinau/motionplus), added /dev/video0 as device in the container.

My motionplus.conf is:

When starting the container it shows the error "Failed to start camera":

I have no idea what I am doing wrong. Can anybody help?
