GetObjectRequest - Error unmarshalling response back from AWS

[lrighetti68]

Hello,

using aw-sdk-delphi TGetObjectRequest I have the error "Error unmarshalling response back from AWS" with any bucket and any object. It's ok using standard delphi component TAmazonConnectionInfo (see attachment)

get.txt

Thanks for your great job!

Are you able to send code that we can reproduce at our side? Maybe a small console project that reads a public S3 bucket?

here it is

In your demo, lower button raises error 403. Upper button raises this error:

[wlandgraf]

"Access key you provided is not in our database".
I cannot reproduce the problem with your project.

I think I understand where the problem is:
The S3 response contains the datetime "Wed, 23 Oct 2024 07:21:43 GMT"
but we are in Italy and the month names are different ("October" -> "Ottobre").

The datetime is checked in TAWSSDKUtils.TryRfc822ToDateTime() calling the function TryStrToDateTime(Copy(S, 5, 20), D, FRFC822FormatSettings);

FRFC822FormatSettings is created in the TAWSSDKUtils.Create class constructor with:
FRFC822FormatSettings := TFormatSettings.Create; without any parameters -> "Initialize a TFormatSettings record with the current default values ​​provided by the operating system" (Italy settings)

To validate the date in a different region we need to create FormatSettings with the parameter 'en-US':
FRFC822FormatSettings := TFormatSettings.Create('en-US');

By doing so I can use the function without any problems.

Thanks a lot!
