Menu Commands Outline Stroke

Thanks for everyone that responded, you all found solutions so I wish I could give everyone correct answer points. And Quertyfly, the way you were able to create and load an action with your script was really cool, If I can figure out what and how the heck you did it would really open up a lot more possibilities for me.

Another way to do it is to use a "Create Outline" effect and then use an "expandStyle" command right afterwards.

    app.executeMenuCommand('Live Outline Stroke');

    app.executeMenuCommand('expandStyle');

Qwertyfly...‌ : when an action is not present, but it is commanded to play, and UserInteractionLevel is DONTDISPLAYALERTS, it seems to not even run the catch block. So, I wonder if the way a script can even tell that there was en error is because the Action error dialog pops up. When they are suppressed, the script seems oblivious.

I think pressing Stop once is a reasonable solution, given our luck of the draw with Actions.
