Hi there, I am posting here to see if the community can to help me.

I am facing an issue where the PDF Export is, apparently, not working properly neither with MS Edge (88.0.705.53) nor on Chrome ( 88.0.4324.104 ), but is working fine on Firefox (84.0.1). When I try to generate the PDF with pictures that are stored on AWS S3 it throws CORS' errors to the Edge/Chrome console as you can see by the attached picture. When I generate the PDF from Firefox it works like charm.



I have read the AWS S3 CORS documentation (, I have read the Mozilla documentation (Cross-Origin Resource Sharing (CORS) - HTTP | MDN (, I have adjusted  my CORS and nothing. 

I have opened a ticket to the support and no one has being able to guide me or fix the issue that happens only on Edge/Chrome.

My CORS configuration, for this test purpose, is like this:

        "AllowedHeaders": [
        "AllowedMethods": [
        "AllowedOrigins": [
        "ExposeHeaders": [
        "MaxAgeSeconds": 3000

I created a DOJO ( that proves that it works on Firefox but does not work on Edge/Chrome. 

So, I would be grateful if anyone can help me solving this.

Hi Pedro,

I have supplied an answer in your other support thread on the same topic that suggests a solution for the issue by utilizing the crossorigin attribute as follows:

<img crossorigin="anonymous" src="..." />

With this modifications, images are now being successfully printed in Chrome and Edge as well:
