Github Actions.
A nice feature that can drive you nuts.

"GITHUB_EVENT_PATH: The path of the file with the complete webhook event payload. For example, /github/workflow/event.json."

"github.event_path: The path to the full event webhook payload on the runner."

Well guess what? These fucking variables are completely useless since the path in them is non-existent.
Fortunately /github/workflow/event.json works...but for how long?

Also using header Accept: application/vnd.github.v3+json to download a zip file is masochism.
