wso2 - WSO2 APIM：登录时管理应用程序在 BPS 的序言中生成意外的 EOF

Question

我们正在配置 WSO2 API 管理器（版本 2.1.0）以使用应用程序创建工作流。

为此，我们配置了一个 BPS 节点（版本 3.6.0），如 https://docs.wso2.com/display/AM210/Adding+an+Application+Creation+Workflow中所述，我们已经完成了描述的调整在 https://docs.wso2.com/display/AM210/Configuring+Workflows+in+a+Cluster 中是必需的，因为我们使用了 2 个不同的节点，具有不同的名称。

现在，应用程序创建过程/工作流似乎工作正常，并且接收和处理批准和拒绝。

但是我们仍然有一个错误。当我们登录管理应用程序 ( https://apimanager.example.com:9443/admin ) 时，我们会在 BPS 节点中看到一个错误。

TID: [-1234] [] [2018-06-18 10:36:20,508]  INFO {org.apache.axis2.builder.BuilderUtil} -  OMException in getSOAPBuilder {org.apache.axis2.builder.BuilderUtil}
org.apache.axiom.om.OMException: com.ctc.wstx.exc.WstxEOFException: Unexpected EOF in prolog

我们在做任何事情之前看到这个错误，在任何情况下（没有任务，有待处理的任务和没有待处理的任务）

很明显，管理员应用程序在登录时调用了 WebService，内容错误，但我们不知道如何调试它。我们如何知道 BPS 节点调用了哪个服务？

任何建议都将受到欢迎。

下面，我们要安装的脚本配置工作流，以及我们正在使用的工作流扩展
