Laravel AJAX 404 for route - php

Question

I am working on a Laravel 5.3 solution. I try to call a POST route via AJAX from one of my views to update a set of categories but I get a 404 error everytime I call the route.
Interesting fact: During development I was able to call the route with the JS-code shown below successfully - but since I did some updates to the controller code itself it throws a 404 but no exception.
Here is my controller action:
public function updateTree( Request $request )
{
$data = $request->json()->all();
$result = BlogCategory::rebuildTree($data, false);
if($result > 0) {
return Response::HTTP_OK;
}
return Response::HTTP_NOT_MODIFIED;
}
And here the JS AJAX call:
$.ajaxSetup({
headers: {
'X-CSRF-TOKEN': $('meta[name="csrf-token"]').attr('content')
}
});
var updateTree = function (e) {
var list = e.length ? e : $(e.target), output = list.data('output');
console.log(JSON.stringify(list.nestable('serialize')));
$.ajax({
url: '{{ action('BlogCategoryController#updateTree') }}',
type: "POST",
data: JSON.stringify(list.nestable('serialize'))
});
};
$(document).ready(function() {
$('#nestable2').nestable({
group: 1
}).on('change', updateTree);
});
The controller route is bound like that in web.php
Route::post( '/service/blog/categories/updatetree', 'BlogCategoryController#updateTree' );
As you might see, I am using the Laravel NestedSet module from LazyChaser here (https://github.com/lazychaser/laravel-nestedset).
Any input is much appreciated.
Cheers,

Answer 1

you having opening and closing quotes problem in your ajax url, use like this
$.ajax({
url: '{{ action("BlogCategoryController#updateTree") }}',
type: "POST",
data: JSON.stringify(list.nestable('serialize'))
});
