Here is the code to reproduce the issue. The error received is internal error in the case of s3-gateway. We receive a proper error in the case of S3.

package main

import (
    "bytes"
    "fmt"
    "log"

    "github.com/minio/minio-go"
)

func main() {
    s3Client, err := minio.NewCore("127.0.0.1:9001", "minio", "minio123", false)
    if err != nil {
        log.Fatalln(err)
    }
    bucket := "mybucket"
    object := "myobj"
    uid, err := s3Client.NewMultipartUpload(bucket, object, minio.PutObjectOptions{})
    if err != nil {
        log.Fatalln(err)
    }

    p1, _ := s3Client.PutObjectPart(bucket, object, uid, 1, bytes.NewReader([]byte{'a'}), 1, nil, nil)

    p2, _ := s3Client.PutObjectPart(bucket, object, uid, 2, bytes.NewReader([]byte{'a'}), 1, nil, nil)

    parts := []minio.CompletePart{
        minio.CompletePart{PartNumber: p1.PartNumber, ETag: p1.ETag},
        minio.CompletePart{PartNumber: p2.PartNumber, ETag: p2.ETag},
    }

    err = s3Client.CompleteMultipartUpload(bucket, object, uid, parts)

    fmt.Println(err)
}
