The pdf getting stored in s3 is not opening and giving an error

Error Failed to load PDF document.

This error appears when I try to open the pdf which gets downloaded by clicking on the url. I have also added the permissions- { "Version": "2012-10-17", "Statement": [ { "Sid": "AllowPutObject", "Effect": "Allow", "Principal": "", "Action": [ "s3:PutObject", "s3:GetObject" ], "Resource": "arn:aws:s3:::applicationsbucket/" } ] }
