load licenseKey on puppeteer project

Hi Team,
i'm trying to use puppeteer project to download a report in background. Everything works fine but when I load the licenseKey properties the command node start doesn't end the task.
 
I load the license in classic mode like below:
 

let pivot = new Flexmonster({
   container: "#pivotContainer",
   licenseKey: "XXX",
   componentFolder: "https://cdn.flexmonster.com/",
.
.
.

 
Is it possible and is it necessary to load license in puppeteer project? How can I do that?
 
Thanks a lot
Ciao
