S3:GetBucketLocation throwing error

[jitcompile]

Calling S3.GetBucketLocation with a bucket name throws the following error. Ideally the exception should be caught, processed and the information shown as LocationConstraint output field.

AuthorizationHeaderMalformed: The authorization header is malformed; the region 'us-east-1' is wrong; expecting 'ap-southeast-2' status code: 400, request id:

Hi @jitcompile thanks for reporting this issue. When you encountered this issue, was the region specified as us-east-1? In addition was the Config.Endpoint value set for this operation request? I'm trying to reproduce the issue you're seeing with the below code, but it's coming back with the correct response.

If you could add your configuration, and even better HTTP body output like in the following sample it would be very helpful.

package main

import (
    "fmt"
    "github.com/aws/aws-sdk-go/aws"
    "github.com/aws/aws-sdk-go/service/s3"
)

func main() {
    svc := s3.New(aws.NewConfig().
        WithLogLevel(aws.LogDebugWithHTTPBody).
        WithRegion("us-east-1"))

    res, err := svc.GetBucketLocation(&s3.GetBucketLocationInput{
        Bucket: aws.String("bucket-thats-in-ap-southeast-1"),
    })

    fmt.Println(res, err)
}

Hi @jasdel,

I've tried to log the http body and here's the printed message. The last line is from my own logging where I log the *aws.config.region value to screen.

Thanks for the extra information. I think I figured this problem out. The GetBucketLocation should be using the S3 path style where the bucket name is apart of the URI path instead of host.

A workaround you can use until this is fixed is in your Config enable S3ForcePathStyle. This will ensure the S3 service client makes the request correctly for cross region bucket information.

svc := s3.New(aws.NewConfig().
        WithS3ForcePathStyle(true)

or

svc := s3.New(&aws.Config{S3ForcePathStyle: aws.Bool(true)})

Thanks @jasdel for confirming the problem and the workaround.

I've a ugly hack in my code where I'm parsing the error using regex and getting the correct bucket location. I'll use the workaround that you suggested.

I'll wait for the final fix. Thank you and fantastic work with the sdk 👍

Hi @jitcompile This bug was fixed in the SDK's latest release. If you sync with it you'll be able to use GetBucketLocation without setting the S3ForcePathStyle config option.
