I'm building a Telegram bot using Aiogram, and I'm encountering a problem where my bot doesn't start when I include the crm_router. However, when I replace it with auto_responder_router, everything works fine.

Here is my code in run.py:

'''

from dotenv import load_dotenv
import os
from aiogram import Bot, Dispatcher
from aiogram.types import Message
from aiogram.filters import CommandStart
import asyncio
from auto_responder import *
from crm import crm_router, init_db
from orders import *
from reminders import *
from admin_panel import *
import logging

logging.basicConfig(level=logging.INFO)
logger = logging.getLogger(__name__)

load_dotenv()
bot = Bot(token=os.getenv('BOT_TOKEN'))
dp = Dispatcher()

@dp.message(CommandStart())
async def start(message: Message):
    await message.answer('Hello! I am a bot. I can help you with your business. Please choose one of the following options: /auto_responder, /crm, /orders, /reminders, /admin_panel')

async def main():
    dp.include_routers(
        crm_router,
        auto_responder_router
    )
    await init_db()
    await dp.start_polling(bot)

if __name__ == "__main__":
    try:
        asyncio.run(main())
    except (KeyboardInterrupt, SystemExit):
        print("Bot stopped!")

code in crm.py:

import asyncpg
import os
from dotenv import load_dotenv
from aiogram.types import Message
from aiogram import Router, F
from aiogram.filters import Command


crm_router = Router()
load_dotenv()

# Глобальная переменная для пула соединений
DB_POOL = None

async def init_db():
    global DB_POOL
    DB_POOL = await asyncpg.create_pool(os.getenv('DB_URL'))

    async with DB_POOL.acquire() as conn:
        await conn.execute('''
            CREATE TABLE IF NOT EXISTS clients (
            id SERIAL PRIMARY KEY,
            name TEXT NOT NULL,
            phone TEXT UNIQUE NOT NULL,
            created_at TIMESTAMP DEFAULT NOW()
        );
        ''')

        await conn.execute('''

            message TEXT NOT NULL,
            created_at TIMESTAMP DEFAULT NOW()
        );
        ''')

async def get_db():
    global DB_POOL
    if DB_POOL is None:
        await init_db()

@crm_router.message(Command('crm'))
async def crm(message: Message):
    await message.answer('Welcome to the CRM system! Write your name and phone number in the format: `Name|Phone` (example: `Jane Doe|+1234567890`)')

@crm_router.message(F.text)
async def handle_crm_message(message:Message):
    """Обработчик текстовых сообщений для CRM"""
    print("CRM text message received")
    if message.text.startswith('/'):
        return

    data = message.text.split('|')
    if len(data) != 2:
        await message.answer('Invalid format! Please use: `Name|Phone`')
        return

    name, phone = data[0].strip(), data[1].strip()
    if not phone.startswith('+'):
        await message.answer('Invalid phone number! Please use the format: `+1234567890`')
        return

    await save_data(name, phone)
    await message.answer(f'Thank you, {name}! Your phone number {phone} has been saved.')

async def save_data(name: str, phone: str):
    await get_db()
    async with DB_POOL.acquire() as conn:
        await conn.execute(
            "INSERT INTO clients (name, phone) VALUES ($1, $2) ON CONFLICT (phone) DO NOTHING",
            name, phone
        )

async def save_message(client_id: int, message: str):
    """Сохраняет сообщение клиента"""
    async with DB_POOL.acquire() as conn:
        await conn.execute(
            "INSERT INTO messages (client_id, message) VALUES ($1, $2)",
            client_id, message
        )

code in autoresponder.py:

Problem: When I replace crm_router with auto_responder_router, the bot starts normally.

When I include crm_router, the bot doesn't start and gives no clear error.

What I've Tried: Checking crm.py for syntax errors.

Ensuring crm_router is properly initialized as a router.

Running init_db() separately to verify it works.

Using print statements for debugging, but no errors appear.
