api error NotImplemented: A header you provided implies functionality that is not implemented.

Hello,

We've been proxying through this wonderful app for a year, and we have had no issues since today.

We are currently using AWS SDK Go v2 to interact with S3Proxy, and we are on both clouds GCP and Azure.

I have manually pinned Docker version to 2.7.0, but I get the same result. With version 2.6.0 it is all good.

The error is: A header you provided implies functionality that is not implemented. for both clouds.

The code is simple:

We connect using:

	// Retrieve the environment variables
	accessKey := configure.Username
	secretKey := configure.Password
	region := "us-east-1"
	endpoint := configure.Url

	// Load the configuration with the environment variables
	cfg, err := config.LoadDefaultConfig(context.TODO(),
		config.WithRegion(region),
		config.WithCredentialsProvider(credentials.NewStaticCredentialsProvider(accessKey, secretKey, "")),
	)

	require.NoError(t, err, "failed to create s3 client")

	client := s3.NewFromConfig(cfg, func(options *s3.Options) {
		options.UsePathStyle = true
		options.Region = region
		options.BaseEndpoint = &endpoint
		options.HTTPClient = &http.Client{
			Transport: &http.Transport{
				TLSClientConfig: &tls.Config{
					InsecureSkipVerify: configure.IgnoreTLSIssues,
				},
			},
		}
	})

We create a bucket and we upload files to the bucket:

func uploadRandomFile(ctx context.Context, client *s3.Client, bucketName string, fileName string) error {

	data := []byte("this is a test")
	reader := bytes.NewReader(data)
	_, err := client.PutObject(ctx, &s3.PutObjectInput{
		Bucket: aws.String(bucketName),
		Key:    aws.String(fileName),
		Body:   reader,
	})
	if err != nil {
		return fmt.Errorf("failed to upload file: %v", err)
	}
	fmt.Printf("File %s uploaded successfully\n", fileName)
	return nil
}

I must also add that bucket creation works fine.

Thanks!

I need some debug logs to better understand this. Can you launch the Docker container with LOG_LEVEL=trace? I suspect that this is related to the newer AWS checksums. If so, building with the latest master may address your symptoms.

@gaul I guess this could be something similar to this: https://github.com/boto/boto3/issues/4392?

(Found this issue because I myself am running into Unknown header x-amz-checksum-crc32 with URI /foo/bar/baz with revision f22cc31 of s3proxy. I'll try disabling this on the client side using the information given here for now: https://cloudnative-pg.io/plugin-barman-cloud/docs/object_stores/#s3-compatible-storage-providers)

For reference, setting these environment variables helped in my case. 🚀
