VB FA extension. Barcodes - qrcodes

Summary:

Hello all,

Please I am stuck with barcodes/qrcodes generation in a basic VB FA extension, that would be accessed from FA.

Sherif kindly shared a demo that works perfect in VB-OIC, my problem is when I try to reproduce the same approach in VB-extension for FA.

I have imported the javascript code, as shown:

This is the error, it seems javascript in js libraries is not ok, but I do not know what to change nor where.
