Hi,

We are using collector node in our interfaces. We are seeing some exceptions raised by some of the interfaces.

Weird thing is that no input message/payload is getting failed. Our common error flow logs the payload attributes to identify the message in case of failure. But we are not seeing any payload getting logged by commmon error flow. Below exception is getting logged by our common error flow:

**************************************************
- <tgt:ExceptionInformation>
<tgt:ExceptionNumber>4395</tgt:ExceptionNumber>
<tgt:Severity>3</tgt:Severity>
<tgt:Category>RecoverableException</tgt:Category>
<tgt:DetailErrorMessage>RecoverableException::Node throwing exception.RecoverableException::Unhandled exception in plugin method..RecoverableException::Unhandled exception in plugin method.->522.</tgt:DetailErrorMessage>
<tgt:ErrorSource>com.tgt.isi.schemas.ISI_SendArticleMasterDataToWMSICC_MsgFlow.AMToWMSICCCollection</tgt:ErrorSource>
</tgt:ExceptionInformation>
**********************************************

And we are able to see the detail error in the Broker log. Below is the message in broker log:

We are using WMB 7.0.3. We are not able to find the root cause for this issue. Any help from the forum is very much appreciated.

Thanks,
