Golang AWS SDK v2 SignatureDoesNotMatch

[frostbyte73]

Bug report

• [✔] I confirm this is a bug with Supabase, not with my own application.
• [✔] I confirm I have searched the Docs, GitHub Discussions, and Discord.

Describe the bug

All operations fail with SignatureDoesNotMatch when using aws-sdk-go v2. The same requests work with s3, minIO, and other s3-compatible providers.

To Reproduce

Steps to reproduce the behavior, please provide code snippets or a repository:

import (
	"context"
	"os"
	"testing"

	"github.com/aws/aws-sdk-go-v2/aws"
	awsConfig "github.com/aws/aws-sdk-go-v2/config"
	"github.com/aws/aws-sdk-go-v2/credentials"
	"github.com/aws/aws-sdk-go-v2/feature/s3/manager"
	"github.com/aws/aws-sdk-go-v2/service/s3"
	"github.com/stretchr/testify/require"
)

const (
	key      = "***"
	secret   = "***"
	endpoint = "https://***.supabase.co/storage/v1/s3"
	region   = "us-west-1"
	bucket   = "***"

	filepath = "/***/playlist.m3u8"
	filename = "playlist.m3u8"
)

func TestSupabase(t *testing.T) {
	opts := func(o *awsConfig.LoadOptions) error {
		o.Region = region
		o.Credentials = credentials.StaticCredentialsProvider{
			Value: aws.Credentials{
				AccessKeyID:     key,
				SecretAccessKey: secret,
			},
		}
		return nil
	}

	awsConf, err := awsConfig.LoadDefaultConfig(context.Background(), opts)
	require.NoError(t, err)

	client := s3.NewFromConfig(awsConf, func(o *s3.Options) {
		o.BaseEndpoint = aws.String(endpoint)
		o.UsePathStyle = true
		o.ClientLogMode = aws.LogRequest | aws.LogResponse | aws.LogRetries
	})

	file, err := os.Open(filepath)
	require.NoError(t, err)
	defer file.Close()

	_, err = manager.NewUploader(client).Upload(context.Background(), &s3.PutObjectInput{
		Body:        file,
		Bucket:      aws.String(bucket),
		ContentType: aws.String("application/x-mpegurl"),
		Key:         aws.String(filename),
	})
	require.NoError(t, err)
}
