python oauthlib : in escape ValueError "Only unicode objects are escapable"

Question

我正在使用 python-social-auth 从我的 Django 应用程序登录社交网络。在我的本地机器上一切正常，但是当我部署到服务器时出现以下错误:

oauthlib.oauth1.rfc5849.utils in escape
ValueError: Only unicode objects are escapable. Got None of type <type 'NoneType'>.

当我没有在我的 django 设置文件中提供我的 OAuth 消费者 key 和 secret 时，我收到了这个错误。它本质上是一个“未找到必需的设置”错误。是否值得检查部署时成功复制的所有设置？
