combine sgdex timegrid with video

Hello. I am new to Roku development and I got lost. I am working on SGDEX timeGrid epg example. For days I have been tracing the code and trying to understand how it works. I was able to make some changes.  I added url to json files so each channel and program has its unique URL. I also examined their video example. What I am trying to do is when clicked on a program item on EPG it should open a video with the URL the program has. Following is the onclick function

     sub OnProgramSelected(event as Object)
        print "Entering TimeGridView.brs OnProgramSelected()"
        timeGrid = event.GetRoSGNode()
        m.top.rowItemSelected = [timeGrid.channelSelected, timeGrid.programSelected]

        
        print timeGrid.programSelected
        print timeGrid.channelSelected
        print m.top.rowItemSelected
        print m.view.content.getChild(0)  'prints the channel
        print m.view.content.getChild(timeGrid.channelSelected).getChild(timeGrid.programSelected) 'prints the program

        myNode = CreateObject("roSGNode", "ContentNode")
        myNode.focusable = false
        myNode.id = 1
        myNode.title = "Live Gaming Sample Content 1"
        myNode.URL = "https://some url.." 'I will pass the program url if this test works

        
        print myNode

        OpenVideoPlayerItem(myNode)


        print "Exiting TimeGridView.brs OnProgramSelected()"
    end sub

I took OpenVideoPlayerItem() function completely from SGDEX video example which is as follows:

   function OpenVideoPlayerItem(contentItem as Object) as Object
      ' Create MediaView Object and set its fields
      video = CreateObject("roSGNode", "MediaView")
      video.content = contentItem
      video.isContentList = false
      ' Set it to start playing, it wont begin playback until show() is called
      video.control = "play"
      ' Show the media view
      m.top.ComponentController.CallFunc("show", {
          view: video
      })
      return video
  end function

When I run the project it gives the following error:

 Interface not a member of BrightScript Component (runtime error &hf3) in pkg:/components/VideoPlayerLogic.brs(36) 036: m.top.ComponentController.CallFunc("show", { 

I do not understand the problem. I don't understand why it does not play and I do not know how to implement it correctly. The funny thing is once it started to play audio only although it gave the same error.
