MinIO SDK GO with FIPS compatibility

Hello,

I am using GO FIPS compliant image with MinioSDK v7.0.80 My program fails while using the following APIs

RemoveObjectWithResult
RemoveObjects

Code

`package main

import ( "bytes" "context" "fmt" "log"

"github.com/minio/minio-go/v7"
"github.com/minio/minio-go/v7/pkg/credentials"

)

func main() { minioClient, err := minio.New("minio:9000", &minio.Options{ Creds: credentials.NewStaticV4("admin", "secretpassword", ""), Secure: false, })

if err != nil {
    log.Fatalf("Failed to initialize MinIO client: %v", err)
}

minioClient.TraceOn(log.Writer())
bucketName := "test-s3-fips"

// Ensure the bucket exists
err = minioClient.MakeBucket(context.Background(), bucketName, minio.MakeBucketOptions{Region: "us-east-1"})
if err != nil {
    exists, errBucketExists := minioClient.BucketExists(context.Background(), bucketName)
    if errBucketExists == nil && exists {
        log.Printf("Bucket %s already exists\n", bucketName)
    } else {
        log.Fatalf("Failed to create bucket: %v", err)
    }
}

// Upload objects programmatically
objectsToUpload := []string{"object1.txt", "object2.txt", "object3.txt"}
for _, obj := range objectsToUpload {
    uploadObject(minioClient, bucketName, obj)
}

// Test RemoveObjectsWithResult
log.Println("Testing RemoveObjectsWithResult...")
//testRemoveObjectsWithResult(minioClient, bucketName, objectsToUpload)

// Re-upload objects for next test
for _, obj := range objectsToUpload {
    uploadObject(minioClient, bucketName, obj)
}

// Test RemoveObjects
log.Println("Testing RemoveObjects...")
testRemoveObjects(minioClient, bucketName, objectsToUpload)

}

func uploadObject(minioClient *minio.Client, bucketName, objectName string) { content := fmt.Sprintf("This is the content of %s", objectName) _, err := minioClient.PutObject( context.Background(), bucketName, objectName, bytes.NewReader([]byte(content)), int64(len(content)), minio.PutObjectOptions{ContentType: "text/plain"}, ) if err != nil { log.Fatalf("Failed to upload object %s: %v", objectName, err) } log.Printf("Successfully uploaded object: %s to bucket: %s", objectName, bucketName) }

func testRemoveObjectsWithResult(minioClient *minio.Client, bucketName string, objectsToDelete []string) { objectCh := make(chan minio.ObjectInfo) go func() { for _, obj := range objectsToDelete { objectCh <- minio.ObjectInfo{Key: obj} } close(objectCh) }()

// Call RemoveObjectsWithResult
errorCh := minioClient.RemoveObjectsWithResult(context.Background(), bucketName, objectCh, minio.RemoveObjectsOptions{})

log.Println("Starting RemoveObjectsWithResult...")
for err := range errorCh {
    if err.Err != nil {
        log.Printf("Failed to delete object %s: %v", err.ObjectName, err.Err)
    } else {
        log.Printf("Successfully deleted object: %s", err.ObjectName)
    }
}
log.Println("Completed RemoveObjectsWithResult.")

}

func testRemoveObjects(minioClient *minio.Client, bucketName string, objectsToDelete []string) { objectCh := make(chan minio.ObjectInfo) go func() { for _, obj := range objectsToDelete { objectCh <- minio.ObjectInfo{Key: obj} } close(objectCh) }()

// Call RemoveObjects
errorCh := minioClient.RemoveObjects(context.Background(), bucketName, objectCh, minio.RemoveObjectsOptions{})

log.Println("Starting RemoveObjects...")
for err := range errorCh {
    if err.Err != nil {
        log.Printf("Failed to delete object %s: %v", err.ObjectName, err.Err)
    } else {
        log.Printf("Successfully deleted object: %s", err.ObjectName)
    }
}
log.Println("Completed RemoveObjects.")

} `

Here is error (similar error for both APIs)
