Start with the iOS NativeDemo flow for a web-to-iOS call, reproduce the crash while generating an answer, and inspect the surrounding logs, including the GLib-GObject assertion and EventSource parsing errors. Done means the call no longer crashes during answer generation and the answer is produced successfully.
