GitHub's contents API only carries the body of files up to 1MB. Above that the response comes back with `encoding: "none"` and an empty body, and PyGithub's `decoded_content` raises `AssertionError: unsupported encoding: none`. openedx-platform's `uv.lock` crossed that limit on 2026-09-14, going from 1043933 to 1089564 bytes, and the weekly upgrade job has failed on it every run since. The PR still gets created and the reviewers tagged, because the crash is in `verify_upgrade_packages` which runs after that, but the package comparison, the summary comments and the `Ready to Merge` label never happen and the job goes red. Read any file that comes back oversized through the git blobs API instead, which serves base64 up to 100MB. https://github.com/openedx/openedx-platform/actions/runs/35679465605/job/106593046814 Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
The upgrade workflow installs `edx-repo-tools[pull_request_creator]` from PyPI unpinned, so the uv.lock fix only reaches the repos that need it once a release goes out. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>

The blobs API handles any size up to 100MB.Tested by running
pull_request_creatoragainst openedx-platform with the real upgrade diff. It got through the failing step and posted the package comparison on openedx-platform#39138, since closed.Version bumped to 4.1.1 so this reaches repos through PyPI.
