Trouble with routings and Ajax: Error 404

I’ve been assigned at work with doing some stuff to an already existing webpage, and one of them is implementing more searchbars based on one already there. I have copied almost everything, but for some reason, I end up with error 404 once I try to make said search.

I’ll post now all snippets of code related to the search I’m creating (searchActByEntity) and the one I’m taking as reference (searchActByDate):

web.php

Route::get("searchActByDate", [ActivityController::class, 'searchActByDate']);
Route::get("searchActByEntity", [ActivityController::class, 'searchActByEntity']);

ActivityController.php

public function searchActByDate(Request $request){

        if($request->ajax()) {
            $query = $request->get('searchActivity');
            $activityTypes = TypeActivity::all();
            if(empty($query)) {
                $activities=Activity::orderBy('dateAct', 'desc')
                ->whereDate('dateAct', '<', date('Y-m-d'))
                ->get();
            } else {
                $activities=Activity::orderBy('dateAct', 'desc')
                ->whereDate('dateAct', '<', date('Y-m-d'))
                ->where('dateAct', 'like', '%'.$request->searchActivity.'%')
                ->orwhere('nameAct','like','%'.$request->searchActivity.'%')
                ->get();
            }

            $total = $activities->count();

            $html = view('dashboard.partials.itemListActivity', [
                'activities' => $activities,
                'activityTypes' => $activityTypes,
            ])->render();

            return response()->json([
                'success' => true,
                'html' => $html,
                'total' => $total,
            ], 200);
        }else{
            return response()->json([
                'success' => false,
                'message' => "Something went wrong!",
            ], 403);
        }

    }

    public function searchActByEntity(Request $request) {
        if($request->ajax()) {
            $query = $request->get('searchEntity');
            $activityTypes = TypeActivity::all();
            if(empty($query)) {
                $activities=Activity::orderBy('dateAct', 'desc')
                ->get();
            } else {
                $activities=Activity::orderBy('dateAct', 'desc')
                ->where('entityAct', 'like', '%'.$request->searchEntity.'%')
                ->get();
            }

            $total = $activities->count();

            $html = view('dashboard.partials.itemListActivity', [
                'activities' => $activities,
                'activityTypes' => $activityTypes,
            ])->render();

            return response()->json([
                'success' => true,
                'html' => $html,
                'total' => $total,
            ], 200);
        }else{
            return response()->json([
                'success' => false,
                'message' => "Something went wrong!",
            ], 403);
        }
    }

showAllActivities.blade.php (where the code executes), inside document.ready

function ajaxAntiguas(datos){
            return $.ajax({
                url:"searchActByDate",
                type:"GET",
                data:{'searchActivity':datos},
                success:function(data){
                    $('#search_listAct').html(data.html);

                }
            })
        }
function ajaxEntity(datos) {
            return $.ajax({
                url: "searchActByEntity",
                type: "GET",
                data:{'searchEntity':datos},
                success:function(data){
                    $('#search_listAct').html(data.html);
                }
            })
        }
$("#searchEntity").on('keyup', function() {
                var query = $(this).val();
                ajaxEntity(query);
            });
$('#searchActivity').on('keyup', function(){

                var query = $(this).val();

                if($('#button-past-act').hasClass('seleccionado')){
                    ajaxAntiguas(query);
                }else if($('#button-nulled-act').hasClass('seleccionado')){
                    ajaxNulas(query);
                }else if($('#button-avaliable-act').hasClass('seleccionado')){
                    ajaxDisponibles(query);
                } else {
                    ajaxCall(query);
                }

            });

As you can see, the other is part of a bigger thing, but I don’t think that’s part of the issue. Anything else you need to see, let me know, cause I’m stumped. Thanks in advance!
