I get an error "dataTables.editor.js:437 Uncaught TypeError: Cannot read property 'error' of undefined" after submit while edit. I am using JQuery 2.1.4 and Editor 1.5.6

and I use Laravel 5.1.41. I guess there is something wrong with validator in laravel because I try to exclude the validator in controller, it run perfectly. I don't know how to fix it.
