Import PSD to AI layer

I am new to scripting in Illustrator.

I am trying to import PSD files into an AI layer.

So far this is my solution.

var TRGdoc = app.documents.add(DocumentColorSpace.RGB, "1920", "1080");

 

var onFile = File( '~/Desktop/jpeger/illDanceREFon_00642.psd' );

var REFon = app.open(onFile);

var LAYon = REFon.layers[0];

var LAYstuffon = LAYon.pageItems[0];

LAYstuffon.selected = true;

app.copy();

TRGdoc.activate();

var TRGlayer = TRGdoc.layers[0];

TRGlayer.selected = true;

app.paste();

It works most of the time but sometimes it hangs up on the paste.  It feels sloppy.

Just wondering if a more elegant solution exists.

Thanks for looking!
