Need help connecting to Amazon S3 storage

Hi Craig,

I actually got this S3 library "https://github.com/tpyo/amazon-s3-php-class" to work on CI4 when I couldn't find anything specific to CI4.
When you shared the info on how to use this via the official SDK you got me interested.

Now the file tested to upload is less that 50Kb and get upload properly via the custom S3 library. The same file gives me a error when I try it via the SDK method.
It would nice we I can get it to work via the SDK.
