python Flet 订阅广播无法正常收到对方消息，怎么解决?

Question

基于flet官方例子修改成异步的订阅后，只能收到发送方自己的消息，求助！

import flet as ftimport flet_fastapiasync def main(page: ft.Page):    page.title = "Flet Chat"    async def on_message_async(msg):        messages.controls.append(ft.Text(msg))        await page.update_async()    await page.pubsub.subscribe_async(on_message_async)    async def send_click(e):        await page.pubsub.send_all_async(f"{message.value}")        message.value = ""        await page.update_async()    messages = ft.Column()    message = ft.TextField(hint_text="Your message...", expand=True)    send = ft.ElevatedButton("Send", on_click=send_click)    await page.add_async(messages, ft.Row(controls=[message, send]))#ft.app(target=main, view=ft.AppView.WEB_BROWSER)app = flet_fastapi.app(main) # You only get your own messages

使用 ft.app(target=main, view=ft.AppView.WEB_BROWSER) 正常，但无法部署到服务端。

已经联系作者，确认是框架的BUG。
