Error uploading user picuture vai Graph api

Question

I'm trying to upload an image from local drive to Graph via the UploadFile api. Here is my code

string filename = "S:\\28-sept\\leo.jpg";
byte[] bytes = File.ReadAllBytes(filename);   

// GetHttpRequest return HtppRequestMessage with Bearer token set. 
// I confirm graphAccessToken is correctly set                   


 var req =  GetHttpRequest(HttpMethod.Put, "https://graph.microsoft.com/v1.0/users/fe7b8732-ca7b-4cc7-b524-4093fc13dfd3e/photo/$value", logger);
 ByteArrayContent streamContent = new ByteArrayContent(bytes);
 streamContent.Headers.ContentType = new MediaTypeHeaderValue("image/jpeg");
 req.Content = streamContent;
    
 var client = new HttpClient();          
 HttpResponseMessage response = client.SendAsync(req).Result;
 string strResp = response.Content.ReadAsStringAsync().Result;

The error:

{
  "error": {
    "code":"**UnknownError**",
    "message": "",
    "innerError": {
      "date":"2024-01-25T16:42:32",
      "request-id":"{{Some-GUID}}",
      "client-request-id":"{{Some-GUID}}"
    }
  }
}

The application permissions are .

Any idea what's going on? Do I have to grant User.ReadWrite.All Application permissions for this?
