minio client (GO SDK) API calls are not working

Question

None of the API calls to perform functions on the minio server running locally works

Here is how I am connecting to the server and listing the buckets

// Use a secure connection.
ssl := false

// Initialize minio client object.
minioClient, err := minio.New("localhost:9000", "minioadmin", "minioadmin", ssl)
if err != nil {
    fmt.Println(err)
    return
}

err = minioClient.MakeBucket("testlalabucket", "")
fmt.Println(err)

Throws error

[] XML syntax error on line 10: element <link> closed by </head>

Using the CLI to communicate with the minio server:

➜  ~ mc ls localminio
mc: <ERROR> Unable to list folder. XML syntax error on line 10: element <link> closed by </head>

Doing another operation (make buckets)

mc: <ERROR> Unable to make bucket `localminio/mylalabucket`. The specified bucket does not exist.
(1) mb-main.go:145 cmd.mainMakeBucket(..) Tags: [localminio/mylalabucket]
(0) client-s3.go:1120 cmd.(*s3Client).MakeBucket(..)

I can access the UI of the minio server to perform all these operation but just not able to do so via the API.

Probably SDK version doesn't match the server version. Here is a complete example which works:

Start the server in docker

docker run -p 9000:9000 minio/minio:RELEASE.2020-02-27T00-23-05Z server /data

Create test.go file as follows

package main

import (
    "log"

    "github.com/minio/minio-go/v6"
)

func main() {
    endpoint := "localhost:9000"
    accessKeyID := "minioadmin"
    secretAccessKey := "minioadmin"
    useSSL := false

    // Initialize minio client object.
    minioClient, err := minio.New(endpoint, accessKeyID, secretAccessKey, useSSL)
    if err != nil {
        log.Fatalln(err)
    }

    bucketName := "testlalabucket"
    err = minioClient.MakeBucket(bucketName, "")

    if err != nil {
        // Check to see if we already own this bucket (which happens if you run this twice)
        exists, errBucketExists := minioClient.BucketExists(bucketName)
        if errBucketExists == nil && exists {
            log.Printf("We already own %s\n", bucketName)
        } else {
            log.Fatalln(err)
        }
    }

    buckets, err := minioClient.ListBuckets()
    if err != nil {
        log.Fatalln(err)
    }

    for _, bucket := range buckets {
        log.Println(bucket)
    }
}

Run GO111MODULE=on go run test.go
