TypeError cannot read property name

I tried creating an installer following the tutorial. I then added a
script called "installerscript.qs" as per the startmenu example in the
Qt Installer Framework directory.

The "installscript.qs" is as follows:

.. code:: qs

    function Component()
    {
        // default constructor
    }

    Component.prototype.createOperations = function()
    {

        component.createOperations();


        if (systemInfo.productType === "windows") {
            component.addOperation("CreateShortcut", "@TargetDir@/customtexteditor.exe", "@StartMenuDir@/open-editor.lnk",
                "workingDirectory=@TargetDir@","iconPath=%TargetDir%/Logo.ico");
            component.addOperation("CreateDesktopShortcut", "@TargetDir@/customtexteditor.exe", "@DesktopDir@/open-editor.lnk", 
                "workingDirectory=@TargetDir@", "iconPath=%TargetDir%/Logo.ico",);
        }
        
    }

My package.xml is as below:

::

    <?xml version="1.0" encoding="UTF-8"?>
    <Package>
        <DisplayName>open-editor</DisplayName>
        <Description>open-editor</Description>
        <Version>1.0.2</Version>
        <ReleaseDate>2019-11-10</ReleaseDate>
        <Default>true</Default>
        <Name>open-editor</Name>
        <Licenses>
            <License name="End User License Agreement" file="license.txt" />
        </Licenses>
        <ForcedInstallation>true</ForcedInstallation>
        <Script>installscript.qs</Script>
    </Package>

When I execute the installer I get the error message:

::

    Exception while loading component script "D:\system\temp\remoterepo-Q2Q7ZU\open-editor\installscript.qs": TypeError: cannot read property 'name' of null on line number: 1

This example worked when I tried it in the example directory. But gives
me the above error when I modify it slightly to work with my own code.

any ideas why it does not work?

i use this command for binary creator:

::

    ..\..\bin\binarycreator.exe --online-only -c config\config.xml -p packages installer.exe
