Amazon.S3.Transfer TransferUtility.UploadAsync() throwing exception under .Net 8 with latest MS and AWS SDK NuGet packages

[AlexanderDarbyVerisk]

Describe the bug

We have updated our Batch tool to run under .Net 8 and also updated all the NuGet packages to the latest, this is now causing a exception to be thrown from the class method TransferUtility.UploadAsync().

If the Batch tool NuGet packages are reverted to old versions then everything works as expected and the file uploads to S3.

The Batch tool is running on the AWS Batch Fargate compute environment.

Previous NuGet package versions when the exception did not happen, worked correctly:

"Amazon.Extensions.Configuration.SystemsManager" Version="5.0.2"
"AWSSDK.Extensions.NETCore.Setup" Version="3.7.5"
"CommandLineParser" Version="2.9.1"
"Microsoft.Extensions.Configuration.Json" Version="6.0.0"
"Microsoft.Extensions.DependencyInjection" Version="6.0.1"
"Microsoft.Extensions.Hosting" Version="6.0.1"
"Microsoft.Extensions.Options.ConfigurationExtensions" Version="6.0.0"
"Serilog.Sinks.Console" Version="4.1.0"
"AWSSDK.RedshiftDataAPIService" Version="3.7.102.9"
"AWSSDK.S3" Version="3.7.103.33"
"CsvHelper" Version="30.0.1"
"JWT" Version="10.0.2"
"Microsoft.Extensions.Options" Version="6.0.0" />
"Polly" Version="7.2.3" />
"RestSharp" Version="109.0.1" />
"Serilog" Version="2.12.0" />

Latest NuGet package versions where the exception is happening, not working correctly:

"Amazon.Extensions.Configuration.SystemsManager" Version="6.2.1"
"AWSSDK.Extensions.NETCore.Setup" Version="3.7.301"
"CommandLineParser" Version="2.9.1"
"Microsoft.Extensions.Configuration.Json" Version="8.0.0"
"Microsoft.Extensions.DependencyInjection" Version="8.0.0"
"Microsoft.Extensions.Hosting" Version="8.0.0"
"Microsoft.Extensions.Options.ConfigurationExtensions" Version="8.0.0"
"Serilog.Sinks.Console" Version="6.0.0"
"AWSSDK.RedshiftDataAPIService" Version="3.7.400.4"
"AWSSDK.S3" Version="3.7.400.4"
"CsvHelper" Version="33.0.1"
"JWT" Version="10.1.1"
"Microsoft.Extensions.Options" Version="8.0.2"
"Polly" Version="8.4.1"
"RestSharp" Version="111.4.1"
"Serilog" Version="4.0.1"

Running under the .Net 8 runtime makes no difference, the S3 method works as expected with the old NuGet package versions. The issue is a NuGet library version update that has introduced a new bug.

Expected Behavior

The method completes successfully and uploads the file to S3.

Current Behavior

The exception details are as follows:

}

Reproduction Steps

Code where the method is called:

public async Task WriteFileToS3Async(Stream stream, string outputFileName)
{
var s3Utility = new TransferUtility(_client);
await s3Utility.UploadAsync(stream, $"{_environmentVariables.S3BucketName}/{_environmentVariables.OutputDir}", outputFileName);
}

The class member '_client' object is a IAmazonS3 interface that is injected on app start-up i.e. 'services.AddAWSService IAmazonS3 ();'

The 'stream' object passed in is a FileStream type.

Hi @AlexanderDarbyVerisk,

Thank you for reporting the issue. To confirm, the new version of AWSSDK.Core is 3.7.400.4 or above, right?

Also, it would be great if you are able to provide a self-contained code sample that can help to reproduce the error reliably.

Regards,
Chaitanya

Hello,

Yes, transitive package referenced from the parent AWS NuGet packages is AWSSDK.Core version 3.7.400.5

The AWS packages being used are:

Amazon.Extensions.Configuration.SystemsManager Version="6.2.1"
AWSSDK.Extensions.NETCore.Setup Version="3.7.301"
AWSSDK.RedshiftDataAPIService Version="3.7.400.4"
AWSSDK.S3 Version="3.7.400.4"

The parent AWS packages also use the following transitive packages:

AWSSDK.AppConfigData version 3.7.301.35
AWSSDK.SimpleSystemsManagement version 3.7.303.23

I expect it would just be a case of trying to upload a file to S3 using the TransferUtility.UploadAsync() method which will cause the exception.

The AWS credentials are automatically obtained through AWS Batch Fargate process.

[AlexanderDarbyVerisk]

It is a bit strange though that the latest stable version of the AWS NuGet package AWSSDK.Extensions.NETCore.Setup is version 3.7.301?

The previous old version was 3.7.5 that we used.

Looks like the latest version number has gone down?

@AlexanderDarbyVerisk Do you still see the error if you change your code to use this instead?

await s3Utility.UploadAsync(stream, _environmentVariables.S3BucketName, $"{_environmentVariables.OutputDir}/{outputFileName}");

The SDK used to support a key prefix (i.e. the / character) in the bucket name but that's no longer the case in the latest version of the AWSSDK.S3 package (see #2622 (comment) for a longer explanation).

@dscpinheiro

That has fixed our issue. Thanks for the help!
