The Gemini Cookbook example in FastAPI doesn't always trigger start_up()

[Zundrium]

I've started with a 1 to 1 copy of the cookbook example and ran the index.html

Sadly sometimes (1 out of 10 times) it runs and other times the start_up method of the GeminiHandler just doesn't run. If I understand correctly this is supposed to run on every new connection.

I've let Gemini search through all possible library files and it fixed it by overriding "set_args" like so:

    def set_args(self, args: list[Any]) -> None:
        print(f"[DEBUG] GeminiHandler: set_args called with {len(args)} args")
        super().set_args(args)
        
        if not self.channel_set.is_set():
            print("[DEBUG] GeminiHandler: Force-setting channel_set event to unblock start()")
            self.channel_set.set()

Instead of never initializing, now it does in around 3 to 5 seconds.

What is going on? Are the examples outdated?
