Hello there,when using 0_download_json.cmd I got：

status: 440
Traceback (most recent call last):
File "0_download_json.py", line 492, in <module>
futures = [executor.submit(download_soul_info, soul_info) for soul_info in soul_infos]
TypeError: 'NoneType' object is not iterable

Can anyone explain how to solve this?
