Breaking OSCI: GitHub's latest changes in event data model

[ihrigb]

GitHub recently introduced changes to some event models that cause the OSCI to break: https://github.blog/changelog/2025-08-08-upcoming-changes-to-github-events-api-payloads/

The commits field (and others) of $.payload was removed. Therefore author's emails are no longer available and OSCI is broken.

An alternative could be the "Compare two commits" API (https://docs.github.com/en/rest/commits/commits?apiVersion=2022-11-28#compare-two-commits), but that would cause a lot of API calls with the problem of authorization, throttling, rate limiting and all that.

Example for old JSON model:

{
    "actor": {
        "avatar_url": "https://avatars.githubusercontent.com/u/3818096?",
        "display_login": "trungnd1",

    },

        "commits": [
            {
                "author": {
                    "email": "[email protected]",
                    "name": "trungnd1"
                },
                "distinct": true,
                "message": "feat: Improve debug info panel layout\n\nRefactors the debug info panel to use a fixed, bottom-aligned layout with improved styling. This makes the panel more accessible and less obtrusive while still providing essential debugging information.",

            }
        ],
        "distinct_size": 1,
        "head": "7d0cba3af297f201f34a2cfa2bb3c972c04f5309",

    },
    "public": true,
    "repo": {

        "url": "https://api.github.com/repos/trungnd1/ai-business-portrait-generator"
    },
    "type": "PushEvent"
}

Example for new JSON model (missing the commits field in payload:
