Hi there,

The error you are seeing is not related to your license key but is related to how you set up [PDFJS.Express](http://PDFJS.Express).

It seems like you are loading the static resources cross origin which causes issues when loading Express. Please see [this guide](https://pdfjs.express/documentation/learn-more/cors) for more information on how to set up cross origin assets.

Thanks!  
Logan
