### Step 3: Test with Thumbnailer

We used [Thumbnailer](https://github.com/minio/thumbnailer) to listen for MinIO notifications when a new JPEG file is uploaded (HTTP PUT). Triggered by a notification, Thumbnailer uploads a thumbnail of new image to MinIO server. To start with, download and install Thumbnailer.

```
git clone https://github.com/minio/thumbnailer/
npm install
```

//
//	STEP 1: Call the handler with the unsigned HTTP request (anonReq), assert for the `ErrAccessDenied` error response.
func ExecObjectLayerAPIAnonTest(t *testing.T, obj ObjectLayer, testName, bucketName, objectName, instanceType string, apiRouter http.Handler,
	anonReq *http.Request, bucketPolicy *policy.BucketPolicy,
) {
	anonTestStr := "Anonymous HTTP request test"
	unknownSignTestStr := "Unknown HTTP signature test"

	ctx, cancel := context.WithTimeout(ctx, 10*time.Second)
	defer cancel()

	req, err := http.NewRequestWithContext(ctx, http.MethodPost, endpoint, bytes.NewReader(buf))
	if err != nil {
		return err
	}

	if token != "" {
		req.Header.Set("Authorization", token)
	}
	req.Header.Set("Content-Type", "application/json")

	clnt := http.Client{Transport: getRemoteInstanceTransport()}
	resp, err := clnt.Do(req)
	if err != nil {

		Host:         handlers.GetSourceIP(r),
	})
}

// multipartReader is just like https://pkg.go.dev/net/http#Request.MultipartReader but
// rejects multipart/mixed as its not supported in S3 API.
func multipartReader(r *http.Request) (*multipart.Reader, error) {
	v := r.Header.Get("Content-Type")
	if v == "" {
		return nil, http.ErrNotMultipart
	}
	if r.Body == nil {
