我试图创建一个简单的 flask 应用程序，将允许我登录和退出使用Firebase，但我得到这个错误。
Firebase ID令牌具有错误的“iss”（颁发者）声明。应为“https://securetoken.google.com/watering-web-app“，但得到的是“https://session.firebase.google.com/watering-web-app“。请确保ID令牌与用于验证此SDK的服务帐户来自同一Firebase项目。有关如何检索ID令牌的详细信息，请参见https://firebase.google.com/docs/auth/admin/verify-id-tokens。
下面是app.py文件的外观，以供参考。

The error is happening in the home page when I try to decode the tokenId.<br>
`decoded_token = auth.verify_id_token(id_token)`
