Hi

There is a process model which has not invoked the reference process and failed with below error in wm.prt.dispatch:invokeCallActivityStart service:

java.lang.NullPointerException: null at com.wm.app.prt.StepDispatcher.handleNativeDoc(StepDispatcher.java:613) at com.wm.app.prt.StepDispatcher.handleSubprocessStart(StepDispatcher.java:223) at wm.prt.dispatch.callActivityStart(dispatch.java:438) at wm.prt.dispatch.invokeCallActivityStart(dispatch.java:377) at sun.reflect.GeneratedMethodAccessor459.invoke(Unknown Source) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:43) at java.lang.reflect.Method.invoke(Method.java:606) at com.wm.app.b2b.server.JavaService.baseInvoke(JavaService.java:443) at com.wm.app.b2b.server.invoke.InvokeManager.process(InvokeManager.java:640) at com.wm.app.b2b.server.util.tspace.ReservationProcessor.process(ReservationProcessor.java:39) at com.wm.app.b2b.server.invoke.StatisticsProcessor.process(StatisticsProcessor.java:49) at com.wm.app.b2b.server.invoke.ServiceCompletionImpl.process(ServiceCompletionImpl.java:243) at com.wm.app.b2b.server.invoke.ValidateProcessor.process(ValidateProcessor.java:49) at com.wm.app.b2b.server.invoke.PipelineProcessor.process(PipelineProcessor.java:171) at com.wm.app.b2b.server.ACLManager.process(ACLManager.java:291) at com.wm.app.b2b.server.invoke.DispatchProcessor.process(DispatchProcessor.java:34) at com.wm.app.b2b.server.AuditLogManager.process(AuditLogManager.java:369) at com.wm.app.b2b.server.invoke.InvokeManager.invoke(InvokeManager.java:544) at com.wm.app.b2b.server.invoke.InvokeManager.invoke(InvokeManager.java:383) at com.wm.app.b2b.server.ServiceManager.invoke(ServiceManager.java:244) at com.wm.app.b2b.server.ServiceManager.invoke(ServiceManager.java:93) at com.wm.app.b2b.server.ServiceThread.execute(ServiceThread.java:38) at com.wm.app.b2b.server.AbstractISThread.run(AbstractISThread.java:69) at com.wm.util.pool.PooledThread.run(PooledThread.java:119) at java.lang.Thread.run(Thread.java:724)

Could someone please help me understand

Hi Harish,

please provide your wM version?

Any further messages in server.log or error log related to this?

Was this working before?

Hi

The version is 9.5. The process was working before and even now. Its just one order that failed with the above error. The process remained in started state without invoking the referenced process.

Hi Harish,

sounds strange then.

Probably some weird data which caused an missing object when publishing to the referenced process?

Regards,
Holger

Harish – Check, is that process waiting for some resource which might caused to hung this process.

Thanks,
