python空响应问题

有一个通过 API 发送请求的异步函数。我需要检查一个空响应，但由于某种原因它print(html_3['items'] is None)说False，虽然响应是空的。问题是什么？

...

async with session.get(f'https://market.csgo.com/api/v2/my-inventory/?key={profiles_dict[1][1]}') as resp_3:
    html_3 = await resp_3.json()
    print(html_3['items'])
    print(html_3['items'] is None)

...
