问题 I knew many questions and issues have been already made. But I can't find out clear answer to solve this issue. I use html2canvas to screenshot my page - with image from amazon s3 (cloudfront, too) I tried almost every answer from SO and html2canvas issues. I setup my S3 CORS to allow all / also set my bucket to public. Also I gave all public access to Everyone (Just to test if it works. I will block them after deploy) Here's my CORS for s3 <?xml version="1.0" encoding="UTF-8"?>
