I have configured the Clair scanner to analyse a Chainguard image for python however it is failing with below error

$ ./clair-scanner -c http://docker:6060 --ip $(hostname -i) -r sast-container-report.json -l clair.log -w clair-whitelist.yml ${BUILD_IMAGE}

I have tried to check if there are any similar issues with Clair scanning with Chainguard images but could not find any. Also, please note that scanning is working for the below distroless image.

gcr.io/distroless/python3-debian12:nonroot

I am not sure why Clair scanning is not working for Chainguard image. Please advise.
