[Suggestion Fix ]GitHub Action Fails Due to Unsupported Encoding in check_images_in_pr.py line 67

[richarddushime]

The GitHub Action for checking images in a pull request fails with the following error:

AssertionError: unsupported encoding: none
Error: Process completed with exit code 1.

The issue occurs in scripts/webp_conversion/check_images_in_pr.py, specifically when trying to decode file contents using contents.decoded_content.decode('utf-8', errors='ignore'). The script assumes that all files retrieved via repo.get_contents(filename, ref=pr.head.sha) will have base64 encoding, but some files are returned with encoding: none, leading to an assertion error.

The majority of the PRs were failing with this same issue , that's why I took a look into it

👍 All image files/references (if any) are in webp format, in line with our policy.

Excellent catch, thanks! I'm never quite sure how to test action changes in staging, but it looks good (and won't break the website), so I am happy to merge it.

To test the Github actions locally you can use the act package see more here

Once merged I will push an empty commit to rerun the checks
