Creating downloadable pdf files in Storyline - an update on earlier methods

Hi,

I have followed the steps above but am getting an issue with CORS with it trying to gain access to the local file - No 'Access-Control-Allow-Origin' header is present on the requested resource. If an opaque response serves your needs, set the request's mode to 'no-cors' to fetch the resource with CORS disabled.

Would this be fixed by hosting the file on a cloud storage system or is there something else that I'm missing?

Thanks
