Faced "Execution timeout (runtime error &h23)" Error in Function Calculation

I make one sample App for Roku. It is as below. MainScene.brs sub init() m.TaskNodeThread = CreateObject("roSGNode", "TaskNodeThread") m.TaskNodeThread.control = "RUN" end sub MainScene.xm...

    Review the documentation on correctly setting up a task

    https://developer.roku.com/docs/references/scenegraph/control-nodes/task.md

    the way you have set this up 'testContentFunction(testData)' will run when created

    MainScene.brs set testdata for task here before "run"

    sub init()
    m.TaskNodeThread = CreateObject("roSGNode", "TaskNodeThread")
        m.TaskNodeThread.TestContent=testData 
        m.TaskNodeThread.observefield("resultContent","onResultContentChanged") 'observe field to see if we are done with task 
        m.TaskNodeThread.control = "RUN" 
    end sub

    sub onResultContentChanged(event) 'called when task completes
       data=event.getdata()
       'do stuff with data here
    end sub

    TaskNodeThread.xml needs and interface for test content

    <?xml version="1.0" encoding="UTF-8"?>
<component name="TaskNodeThread" extends="Task" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="https://devtools.web.roku.com/schema/RokuSceneGraph.xsd">
     <interface> 
        <field id = "resultcontent" type = "node" />
    <field id = "testcontent" type = "node" />
  </interface>
    <script type="text/brightscript" uri="pkg:/components/TaskNodeThread.brs" /> </component>

    TaskNodeThread.brs m.top.functionName is what is called when .control="run" is set

    sub init()
         m.top.functionName = "testContentFunction"
end sub

    function testContentFunction() as String
        testdata=m.top.testcontent
        'do stuff here
        m.top.resultContent = resultOfStuffDone 'signal task has completed
    end function

Thank you so much for your response. That's what I was looking for.
I read this documentation for stopping the Task node. Is there any way or field available for the Stopping the Task Thread between the Logic?

like

m.TaskNodeThread.control = "STOP"

And

I take the type array in the field and use it like below. But it gives this error => Interface is not a member of BrightScript Component (runtime error &hf3). Is it the correct way I used it?

TaskNodeThread.xml

<field id = "resultcontent" type = "node" />

TaskNodeThread.brs

function testContentFunction() as String

     testdata=m.top.testcontent
     'do stuff here

      for val = 0 to Value - 1
          m.top.resultContent.Push(Value[val])
      end for

   return ""

end function

The single value, I am able to fetch using event. But, I need to fill this whole value in an array.
Using Global value I am able to do
But, only assocaaray available in Global Node.

 

So, I need to convert array to assocarray in Task Thread and Render thread I again convert to assocarray to array and used. This is right approch or you suggest me to any better approch?

 m.global.addfield("resultContentResponse","assocarray", TRUE)

 

TaskNodeThread

contentArr = CreateObject("roArray",Value.Count(),false)
for val = 0 to Value - 1 
     contentArr.Push(Value[val]) 
end for
assocArrayContent = formatJSON(contentArr)
m.Global.resultContentResponse = assocArrayContent

 

MainScene

response = ParseJson(m.Global.resultContentResponse)
'do stuff here 
For Each res In response
     Print "My Response here: " + res 
End For

    Sure... you should be able to m.TaskNodeThread.control = "STOP" at some point in your mainscene after the task has been started.

    if you need to return an array change the type to array. same with test content if you want to pass as a different type such as "string".

    <field id = "resultcontent" type = "array" />
    <field id = "testcontent" type = "string" />

    if you do this like below, then it will trigger the onResultContentChanged() in the mainscene each time you push to the array since this is what is being observed.

         for val = 0 to Value - 1
          m.top.resultContent.Push(Value[val])
      end for

     Do something like this instead

          resultContent=[]
         for val = 0 to Value.count() - 1 
          resultContent.Push(Value[val])
      end for
    m.top.resultContent.append(resultContent) 'only trigger once you are done

    I don't think you want to store this in the GlobalAA node to pass the data

    from mainscene you can access the result 

    response = m.TaskNodeThread.resultContent
