【问题描述】：
我在 Windows 2012 R2 服务器上运行了 WSO2 API 管理器，并且所有仪表板 URL （如 https://localhost:9443/store、https://localhost:9443/carbon、https://localhost:9443/publisher）都可以正常工作。但是当我配置和部署（在 carbon.super 租户中）示例 WeatherAPI Web 服务并尝试通过 /services/... URL 访问它时，即：
https://localhost:9443/services/weather/1.0.0/*?q=Amsterdam
我得到以下错误页面返回：

当我在租户中创建自己的 Web 服务并部署它时，我遇到了同样的错误。所以我可能错误地配置了一些东西，但不知道在哪里看。
/services/... 下面的所有路径似乎都返回了这个错误页面。我检查了[WSO2]/repository/logs 目录中的日志文件，但它们没有显示任何错误。
