Raspberry Pi Cameras

I am using python sdk for AR0234 camera, the camera is working fine but I am getting the following logs continuously through out the time camera is running. How can I fix this.

[2:32:50.622426107] [7046] ERROR Serializer control_serializer.cpp:579 Can't deserialize ControlList: unknown ControlInfoMap
[2:32:50.654665237] [7046] ERROR Serializer control_serializer.cpp:579 Can't deserialize ControlList: unknown ControlInfoMap

[2:32:50.713575294] [7046] ERROR Serializer control_serializer.cpp:579 Can't deserialize ControlList: unknown ControlInfoMap

I used the guide from here How to install and build Raspberry Pi Kernel Driver for Arducam Pivariety Camera to install the drivers and used libcamera-1.0.2-cp39-cp39-linux_armv7l.whl to install the python sdk.

hi, @rash8327

This may be caused by the code about ControlList in the program.

hi, @rash8327

Sorry, this problem is caused by the current Libcamera Python library is not compatible with the latest libcamera-dev.

We originally planned not to maintain this library and fully support Picamera2. However, after testing, Picamera2 does not support autofocus. All we decided to continue to maintain this library until Picamera2 supports all the functions of our camera.
