This was working up until recently, I am not sure what has changed. I am generating a presignedUrl using S3 SDK and uploading a file to a bucket using it. The file actually uploads and the response returns a statusCode of 200 but weirdly there no response body.
I cannot understand if I'm missing some sort of header, or if they're wrong. The Content-length on the response headers worries me.
Any help would be much appreciated!
Note: I've obscured the values, if they are helpful I can mock them back in

I reproduced it using go SDK to confirm it is how API itself behaves, not something specific from nodejs.
As I can see from my experimentation it is a normal behavior now, it will not return anything from PUT request.
OBS: I masked some sensitive values!
The Code:
package main import ( "crypto/tls" "fmt" "log" "net/http" "net/url" "strings" "time" "github.com/aws/aws-sdk-go/aws" "github.com/aws/aws-sdk-go/aws/session" "github.com/aws/aws-sdk-go/service/s3" ) func main() { sess, err := session.NewSession(&aws.Config{ Region: aws.String("eu-west-1")}, ) svc := s3.New(sess) req1, _ := svc.PutObjectRequest(&s3.PutObjectInput{ Bucket: aws.String("bucketversioningenabled"), Key: aws.String("myKey"), Body: strings.NewReader("EXPECTED CONTENTS"), }) presignURL, err := req1.Presign(time.Minute * 1) if err != nil { log.Println("Error on presign", err) return } fmt.Println("Presign: ", presignURL, err) fmt.Println("") req2, err := http.NewRequest("PUT", presignURL, strings.NewReader("EXPECTED CONTENTS")) if err != nil { log.Println("error creating request", err) return } fmt.Println("NewRequest: ", req2, err) fmt.Println("") proxyURL, err := url.Parse("http://myfiddler.proxy.com:8888") if err != nil { log.Println("Error on proxy parse", err) return } tr := &http.Transport{ TLSClientConfig: &tls.Config{ InsecureSkipVerify: true, }, Proxy: http.ProxyURL(proxyURL), } client := &http.Client{ Transport: tr, Timeout: time.Duration(5 * time.Second), } resp, err := client.Do(req2) if err != nil { log.Println("error on request put", err) return } fmt.Println("Do: ", resp, err) } The execution output:
Please loot the Content-Length:[0] on the last line.
