Oauth 2.0 通用身份验证在授权jupyterHub上使用HTTP/500进行响应

集线器服务器日志

Generic authentication fails following oAuth2 authorisation, and produces an uncontextualised and unhandled HTTP/500 error.

Context
The hub and the authentication servers are run on separate Docker containers. They are both served through Nginx, which itself is housed on a a container that is independent of the two servers.

The hub runs on a subdomain, and all proxies are handled by Nginx.

The authorization is handled through the Spring oauth 

The authentication server has been tested separately and is fully operational.

集线器服务器永远不会通过授权来开始处理令牌和用户数据。您可以看到，当集线器服务器尝试通过身份验证服务器解析回调时，而不是在请求令牌时，会发生此错误。GET请求是在auth服务器中的授权之后的请求。这就是为什么这很奇怪的原因。

使用KeyClope处理同一问题。有什么解决方案吗？我也有同样的问题。。。
