Providing a way to handle toast content on ajax error

[leocdi]

Hi, when an error happens in controller, the exeption got fully displayed in the error toast. Would it be possible to have a way to control whats's displayed in case of ajax error ?

My exemple action triggered on submit :

[HttpPost]
[FormValidator]
[ValidateAntiForgeryToken]
public async Task<IActionResult> EditArticleVentePartial(ArArticleVente arArticleVente)
  {
     throw new Exception("You can't catch me");
  }

Formhelper.js related part :

  error: function (request, status, error) {
      console.error(request.responseText);
      formHelperToastr.error(request.responseText, null, toastrOptions);
  }

As we can see, full exeption got displayed in the toast.
