Task with unknown item is sent to assignee

I've edited my files:

iii) review.js

var workflow = actions.create("start-workflow");
workflow.parameters.workflowName = "jbpm$wf:review";
workflow.parameters["bpm:workflowDescription"] = "Sila review dokumen ini";
workflow.parameters["bpm:assignee"] = "us1";
workflow.parameters["bpm:approveDestination"] = "Sites/test-script";
workflow.execute(document);

I get the move my file after approval as I wanted.
The funny thing is, a task with unknown item is sent to assignee us1 everytime after us1 clicks approve during review. The item cannot be accessed at all, as if it has been moved or deleted..
What's happening here?

Is

<prop key="redeploy">true</prop>
‍‍‍

line the cause?

EDIT: sorry, posted the wrong processdefinition code.

This is only to allow your changes to be picked up by JBPM.
I think in your case once you approve transition leading you to end task. And attached item is already moved that might be the reason you are not able to see anything.May be you can try moving you script piece in between transition from "approve" to "approved"

But problem now is the workflow sends two tasks.
One review task is with the correct item, but once the reviewer clicks approve, this file move to the correct folder, but then, the workflow sends in a different task to review (again) of an unknown item. Do you mean that this unknown item is actually the same item that has been moved?

I'm moving the codes now, will update soon.

It seems those code you pasted out will not trigger  sending another  task to review (again).
you can turn debug log on and add some log information in your script to trace what cause your review task created twice and what on earth  "unknown item" is

I don't think it is caused by

<prop key="redeploy">true</prop> ‍

,this flag tells alfresco whether or not it should automatically redeploy the process on startup.

Thanks for the explanation.
I use the same code on review_pooled_processdefinition, and it works. I must have missed something on review_processdefinition..
