I want to upload images to a bucket using a pre-signed URL:

aws s3 presign s3://mybucket/something1.png --expires-in 7200

and just for testing other types:

aws s3 presign s3://mybucket/CV.pdf --expires-in 7200

note that the bucket has no policies in place right now.
I upload the files using this curl command:

curl "presign-url" --upload-file ~/Desktop/CV.pdf
curl "presign-url" --upload-file ~/Desktop/something1.png

in both cases:

as you can see, an extra “” is added at the end of they key and the type. I also considered using commands like:

curl -T ~/Desktop/something1.png -H "Content-Type: image/png" "presign-url"

but I get an error like this:

<?xml version="1.0" encoding="UTF-8"?>
