Python telegraph асинхронный upload изображений, как сделать?

Question

[Resolut]

Загружаю изображения в telegraph таким способом, но при большом количестве изображений это занимает безумно много времени, как можно ускорить и сделать асинхронно? Буду рад если подскажете и покажите пример)

def upload_images(self, chapter: int):
        array_path = list()
        file_list = sorted(os.listdir(f'{chapters_path}/{chapter}'))
        for index, image in enumerate(file_list):
            with open(f'{chapters_path}/{chapter}/{image}', 'rb') as f:
                array_path.append(requests.post('https://telegra.ph/upload',
                    files={'file': ('file', f, 'image/jpg')}
                ).json()[0]['src'])
        return array_path

async def upload_images():
    array_path = list()
    file_list = sorted(os.listdir('image/'))
    for index, file in enumerate(file_list):
        async with aiohttp.ClientSession() as session:
            async with session.post('https://telegra.ph/upload', data={'file': ('file', file, 'image/jpg')}) as response:
                array_path.append(await response.text())

через aiohttp не выходит, пишет

The above exception was the direct cause of the following exception:

Resolut, aiohttp ssl context

Используйте aiohttp либо httpx в качестве HTTP-клиента вместо Requests, т.к. последний не поддерживает asyncio.
