Problem with FLET_WEBSOCKET_HANDLER_ENDPOINT #3585

Open devkam opened 4 months ago

devkam commented 4 months ago

Duplicate Check

Describe the bug

I tried to change the websocket endpoint's path, but it generated errors.

Flet code:

import flet as ft

def main(page: ft.Page):
    page.title = "Web interface"
    page.padding = 0

app = ft.app(target=main, export_asgi_app=True)

default settings (everything is fine here):

SET FLET_WEBSOCKET_HANDLER_ENDPOINT=/ws
uvicorn main:app

custom settings:

SET FLET_WEBSOCKET_HANDLER_ENDPOINT=/websocket
uvicorn main:app

logs:
