Adding this for anyone who has same issue. I plan to add github issue as well but maybe can get it resolved.
I get below error with HA 2021.11.3 in docker
Platform error: image_processing

ImportError: Unable to find zbar shared library
I check and find below issue. seems it is temporary fix but longterm is add pyzbar or zbar to docker image
