Describe the bug

page.client_storage.get_async does'n work when called from page.on_connect callback.
Here is a sample code:

import flet
import flet as ft
from flet import (
    Page,
    colors
)


async def on_connect_callback(e):

    try:
        await e.page.client_storage.get_async('token')
    except Exception as e:
        print(e)


async def main(page: Page):
    print("ddd")
    page.on_connect = on_connect_callback
    page.title = "Flet Trello clone"
    page.padding = 0
    page.bgcolor = colors.BLUE_GREY_200
    page.views.clear()
    page.views.append(flet.View(

        appbar=flet.AppBar(title=flet.Text("sdf"), bgcolor=colors.GREEN)
    ))

    await page.update_async()

In the code I contained the get_async call in a try block and I printed the resulted exception and it says:
**Timeout waiting for invokeMethod clientStorage:get({'key': 'token'}) call
**

I ran the code with fastapi like this:

from fastapi import FastAPI, Request, WebSocket
from fastapi.responses import RedirectResponse

from api.common.db.sql import engine
from api.auth import router as auth_router
from api.config import BASE_DIR
from sqlmodel import SQLModel
import flet_fastapi
from ui.main import main as main_ui

app = FastAPI()

@app.on_event("startup")
async def startup():
    SQLModel.metadata.create_all(engine)
    pass

flet_fastapi_app = flet_fastapi.app(main_ui)
app.mount('/ui', flet_fastapi_app) # this is where we mount the felt to fastapi
#
app.include_router(
    router=auth_router,
    prefix='/auth'
)
@app.get('/')
async def home():
    return RedirectResponse('/ui')

command: uvicorn main:app --reload
But I wanted to check if it happens when running with felt only. so, I created a test.py file and comply the ui/main.py UI code and then:
command: felt test.py --web
This time it doesn't show any error.

    await page.update_async()

from fastapi import FastAPI, Request, WebSocket
from fastapi.responses import RedirectResponse

import flet_fastapi

app = FastAPI()



flet_fastapi_app = flet_fastapi.app(main_ui)
app.mount('/ui', flet_fastapi_app) # this is where we mount the felt to fastapi
#
app.include_router(
    router=auth_router,

@app.get('/')
async def home():
    return RedirectResponse('/ui')

To reproduce

/ represents the root of the project

1. copy the main_ui code into a separate file /ui/main.py
2. copy the main.py code /main.py
3. copy the test.py code into /test.py
4. run main.py with uvicorn main:app --reload for running the felt with fastapi
5. run test.py with flet test.py --web for running with flet
