Data Not Being Passed from Parent Router's Filter to Handler in Inherited Router

[Latand]

Checklist

• I am sure the error is coming from aiogram code
• I have searched in the issue tracker for similar bug reports, including closed ones

Operating system

Windows 10

Python version

3.10

aiogram version

3.0.0rc1

Expected behavior

When the command "/admin" is sent to the bot, the filter AdminFilter should identify whether the text "admin" is present in the message. If it is, the is_admin variable should be passed to the admin_command_handler, allowing it to execute its logic.

Current behavior

The variable is_admin is not being passed to the admin_command_handler, resulting in an error indicating that the variable is not defined.

Steps to reproduce

1. Replace "YOUR_TOKEN_HERE" with your bot token in the code snippet.
2. Run the code.
3. Send the "/admin" command to the bot.
4. Observe the error indicating that the variable is_admin is not defined.

Code example

import asyncio
import logging
import sys

from aiogram import Bot, Dispatcher, Router
from aiogram.filters import BaseFilter, Command

dp = Dispatcher()
token = "YOUR_TOKEN_HERE"
bot = Bot(token)


class IsAdmins(BaseFilter):
    async def __call__(self, message):
        if "admin" in message.text.casefold():
            return {"is_admin": True}
        return False



async def admin_command_handler(message, is_admin: bool):
    await message.answer(f"Admin Command Handler, is_admin: {is_admin}")



admin_router = Router()
admin_router.message.filter(IsAdmins())

admin_command_router = Router()

admin_router.include_router(admin_command_router)
dp.include_router(admin_router)

admin_command_router.message.register(adm_com_router, Command("admin"))


async def main():
    await dp.start_polling(bot)


logging.basicConfig(level=logging.INFO, stream=sys.stdout)

asyncio.run(main())
