Uploader failure event's reponse property does not include the body

Question

https://ej2.syncfusion.com/angular/documentation/api/uploader/#failure

The object emitted by the failure event (see below) has an undocumented property called 'response', which does not include the response body. Is there any way to access the body of the response in the event of plo?

Hi Joseph,We cannot pass
the response body in our failure event argument response attribute. Please update
your exact use case scenario to access the response body. We will update the
exact solution based on your scenario as earlier as possible.Regards,Sureshkumar P

I would like to access the response body after a file fails to upload because our server sometimes includes useful information explaining the reason for the failure in the response body.

This is a very common use case, hence the existence of things like the problem details standard: https://datatracker.ietf.org/doc/html/rfc7807

Based on your requirement, we suspect that you want to
get the status code and status text in the failure event. We suggest you remove
the Response.Clear and Response.ContentType from your server-side code
to achieve your requirement.

[Server
  Side (Razor Page)]
   
  public IActionResult
  OnPostUpload(IList<IFormFile> uploadFiles)
  {
     //... 
          // no need to update the Response here  
          @* Response.Clear(); 
          Response.ContentType = "application/json"; *@ 
          // Sennd HTTP 200 (OK), 400, or what you want. 
          return StatusCode(204, new { Message = $"{errorMessage}" }); 
  }
   
  [Client Side]
     
  function onUploadSuccess(args) {
       
    let response = JSON.parse(args.e.target.response);
       
    args.statusText = response.message;
      }

function onUploadFail(args) {
       
    let response =
  JSON.parse(args.e.target.response);
          args.statusText =
  response.message;
      }

This is a very bad answer. I definitely do not want to clear the response because that is where the information I want to access is located. There are no changes required to the server-side code. I want to access the response body on the client-side after an upload fails. Is that possible?

Hi Joseph,We suggest you pass the text in the response header section and parse the response header in the success or failure event like our previous suggestion. Also, can you please share the back-end service platform details like whether it is in ASP Net Core or MVC? Based on your shared details, we will validate it on our end and update the further details.Regards,Sureshkumar P
