error deserializing GitHub release: {err:?}

Error message

error deserializing GitHub release: {err:?}

What it means

Fires in get_release_by_tag_name after a successful (non-client-error) GitHub API response whose body could not be parsed into a GithubRelease via serde_json. The HTTP call succeeded, but the payload is not the expected release JSON shape — typically because the tag resolved to an unexpected resource, GitHub returned a non-release JSON envelope (e.g. rate-limit or error body with a non-4xx status), or the GithubRelease struct no longer matches GitHub's current API schema.

Solutions

1. Check the full response text logged at error level to see what GitHub actually returned before assuming a code bug
2. Verify the requested tag/URL points to a real GitHub release endpoint
3. Update the GithubRelease struct to match GitHub's current REST API schema if fields changed
4. Retry later if GitHub was returning a transient error body with a 2xx/5xx status
