                                $.notify(data.errors[error], "danger");
                            }
                        }
                    }

            }, 1000);



    });
</script>

There are many reasons for this problem. Maybe you can try to check all below:

1. Check about csrf-token send with your ajax post. Try to add _token: $('meta[name="csrf-token"]').attr('content') into data send.
2. Check about your route.
3. DataType return
4. You need check about your server config. (htaccess, permission...)
