我试图通过Flask与android管理api进行交互。每次我遇到一个我不理解的错误，因为我对编码还很陌生
调用device_list = androidmanagement.enterprises().devices().list(parent=enterprise_name, pageSize=200).execute()时出现错误
我只是不明白我为什么会犯这个错误。
如果有人能解释这是怎么发生的，我会非常高兴。
非常感谢
我在app.py 中的代码

所以我发现了问题是如何出现的：
有3个模块在执行相同的任务谷歌API客户端烧瓶请求请求
这导致了代码冲突。
将在我的API调用工作后更新
