我认为这是某种类型的通用 MuleSoft 错误消息,基本上是说它对输入或输出不满意,但我已经做了我能做的最简单的流程,据我所知,没有要传递的参数。
我正在尝试执行的测试流程:
HTTP -> ZenDesk/ListTickets -> Set Payload ("hello world")
我看过的东西:
在浏览器中,我得到:
null (java.lang.UnsupportedOperationException). Message payload is of type: ZendeskConnector$1
在控制台中,我看到:
Message : null (java.lang.UnsupportedOperationException). Message payload is of type: ZendeskConnector$1
Code : MULE_ERROR--2
--------------------------------------------------------------------------------
Exception stack is:
1. null (java.lang.UnsupportedOperationException)
org.mule.modules.utils.pagination.PaginatedCollection:84 (null)
2. null (java.lang.UnsupportedOperationException). Message payload is of type: ZendeskConnector$1 (org.mule.api.MessagingException)
org.mule.execution.ExceptionToMessagingExceptionExecutionInterceptor:35 (http://www.mulesoft.org/docs/site/current3/apidocs/org/mule/api/MessagingException.html)
--------------------------------------------------------------------------------
Root Exception stack trace:
java.lang.UnsupportedOperationException

+ 3 more (set debug level logging or '-Dmule.verbose.exceptions=true' for everything)

最佳答案
这是类型转换错误......你的消息来自zendesk是特定的类对象所以请我们转换器来转换消息并且它会正常工作......
关于骡子 + ZenDesk : Unhelpful error message: "null (java.lang.UnsupportedOperationException). Message payload is of type: ZendeskConnector$1",我们在Stack Overflow上找到一个类似的问题:https://stackoverflow.com/questions/23257647/
