We are experiencing intermittent missing webhook events with our Server-to-Server OAuth app.
The app has been working as expected for a long time, but recently we noticed that some webhook events are not being delivered. The missing webhooks are not consistent also, some events for a meeting are received successfully, while other expected events for the same meeting are never received.
We checked our Laravel application logs, and our logging is the first operation performed when a webhook request reaches our application. For the missing events, there are no log entries at all. We also checked our server access logs and could not find any record of those missing webhook requests reaching our server.
