After successful ajax request trigger .fail?

Question

JavaScript

Good afternoon, there is a put request to the server of this type:

const params = {
      url,
      method: 'PUT',
      contentType: 'application/json'
    };

    return $.ajax(params)
      .done(() => {
        
      })
      .fail((error) => {
        
      });
  }

The code is successfully executed and saves the sent data on the server, the server responds with OK 200, but then ajax does not run done, but .fail, what could be the problem?

Answer 1

fail must take 3 arguments
xhr, status, error. You can add them to the options and what comes in them.
Maybe the text of the error will help.
