我创建了一个mule进程API，通过mule <http:request>标记使用HTTP请求调用mule系统API。系统API依次使用数据库调用处理请求。流程和系统API部署到云中心。我可以在本地和云中心成功测试系统API。过程API虽然给出了以下错误消息。
********************************************************************************

错误引用了流程API的文件implementation.xml中的第25行。该文件的内容如下所示。第25行是对global.xml中定义的http：request配置程序的调用。
<sub-flow name="getTermsImpl">
<http:request config-ref="httpRequestConfig-sisinfo" path="api/terms" method="GET" doc:name="httpSisInfoTerms">
</http:request>
</sub-flow>
非常感谢任何帮助！
