HttpErrorResponse 200 after successfull POST in Angular

Question

I upload one file from Angular 5.xx to Jersey 1.xx via FormData.

The data gets received and saved successfully on my server app directory, but Browser says this line

Answer 1

Try to actually send a JSON response, or tell angular to expect something different. If you're using HttpClient, it will by default expect JSON.

Something like this:

this.http.post(url, body, { responseType: 'text' }).subscribe();
