When invoking this endpoint [Events APIs - API - Zoom Developer Docs](https://developers.zoom.us/docs/api/events/#tag/attendee-actions/patch/zoom_events/events/%7BeventId%7D/attendee_action) to check-in Event attendees and something goes wrong, documentation says we should expect a response that looks like this:

However, the actual response looks like this:

```auto
{
    "errors":[
        {
            "email":"bob@example.com",
            "error_message":"No access."
        }
    ]
}

```

Notice the documentation mentions a node called “message” but in reality this node is called “error\_message”.
