Upload failed: deploying to S3 using AWS CLI

I have setup AWS CLI and S3 policy/permissions. I am using the ICARUS theme on a MacBook Air. With “hugo serve” the website looks perfect. Then I do “hugo” to generate the public files. All of them are generated in the public folder. I then copy those files in the public folder to another folder, to do a sync to S3 using AWS CLI. Here is what I get (first few lines, and then the last line, since the output is very long):

$ aws s3 sync . s3://aws-website-mybucket --acl public-read --exclude ‘*.DS_Store’
