Share ajax to REST workflow API

[matjazmuhic]

I have share client side javascript and I bound onClick event on my element in my webscript (get.html).
In onClick function I do this:

onClick: function MyTasks_onClick(e){                        Alfresco.util.Ajax.request(                        {                                method: "POST",                                url: "http://localhost:8080/share/proxy/alfresco/api/workflow/task/end/jbpm$58/approve",                                successCallback: { fn: this.onSuccess, scope: this },                                failureMessage: "",                                execScripts: true                        });}onSuccess: function MyTasks_onSuccess(){           alert("Success");}‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍

But I get error from server saying:

{
    "status" :
  {
    "code" : 500,
    "name" : "Internal Error",
    "description" : "An error inside the HTTP server which prevented it from fulfilling the request."
  }, 
 
  "message" : "03150012 Wrapped Exception (with status template): 03150024 Failed to execute script 'classpath*:alfresco\/templates\/webscripts\/org\/alfresco\/repository\/workflow\/end-task.post.js': 03150023 Failed to signal transition approve from workflow task jbpm$58.", 
  "exception" : "org.springframework.extensions.webscripts.WebScriptException - 03150012 Wrapped Exception (with status template): 03150024 Failed to execute script 'classpath*:alfresco\/templates\/webscripts\/org\/alfresco\/repository\/workflow\/end-task.post.js': 03150023 Failed to signal transition approve from workflow task jbpm$58.",

So basically it says "Failed to signal transition approve from workflow task jbpm$58." Task DOES exist and it has two transitions: approve and reject.
I have no clue what's wrong here.

Help?

Don't have a direct answer to your problem, but I found a nice debug tool for resful services.

I added the plugin poster to my firefox.
   it allows me to send gets and posts to me backend.
 
I can tweek my json until I get it just right.
   saved me a lot of time.

it looks like you may have some type of index missing.
