Due to the inability of the lens to focus,oak-d-lite can be calibrated.

Hi there, I was using depthai python to calibrate the Oak-d-lite camera and found that the RGB lens couldn't focus. The calibration program cannot be executed. But starting the camera alone, all lenses focus well.
Could you help me take a look at this issue? Thank you very much！
