Bug
using aiokafka consumer getmany method, error : 'NoneType' object has no attribute 'check_errors'

Raise coordination errors if any
self._coordinator.check_errors() # self._coordinator is None

producer code as blow:

from aiokafka import AIOKafkaProducer
import asyncio


async def producer():
    p = AIOKafkaProducer(bootstrap_servers='localhost:9092')
    await p.start()
    try:
        await p.send("my_topic", b"my_topic")
    finally:
        await p.stop()


if __name__ == '__main__':
    asyncio.run(producer())

consumer code as blow:

import asyncio
from aiokafka import AIOKafkaConsumer


async def consumer():
    consume = AIOKafkaConsumer(
        'my_topic',
        bootstrap_servers='localhost:9092',
        group_id="my-group",
        auto_offset_reset='earliest',
        )
    try:
        data = await consume.getmany()
        for tp, msgs in data.items():
            print(tp.topic, tp.partition)
            for msg in msgs:
                print(msg.offset, msg.key, msg.value)
    except Exception as e:
        print(e)
    finally:
        print('finally')
        await consume.stop()


if __name__ == '__main__':
    asyncio.run(consumer())
