This keeps occurring with our stereo cameras. It seems like they work when they are outside of our body, but the second we mount them we get this error. the ribbons are not touching. Hires and tracking are working. Any suggestions would be greatly apprecaited

My fault. Found a small tear in the ribbon for the stereo cameras
