Target class [App\Sys\Http\Controllers\Api\LocationController] does not exist - laravel

Question

I have setup Laravel 6 project but for some reason when php artisan route:list returns “Target class [App\Sys\Http\Controllers\Api\LocationController] does not exist." I'm new in Laravel and I can't understand why the controller doesn't work. Can anyone please help me?
Here are my code:
LocationController.php
<?php
namespace App\Http\Controllers\Api;
//use App\Http\Controllers\Controller;
use Illuminate\Http\Request;
use App\Location;
class LocationController extends Controller
{
public function index(Request $request)
{
$per_page = $request->per_page ? $request->per_page : 5;
$sort_by = $request->sort_by;
$order_by = $request->order_by;
return response()->json(['locations' => Location::orderBy($sort_by, $order_by)->paginate($per_page)],200);
}
public function store(Request $request)
{
$location= Location::create([
'code' =>$request->code,
'name' =>$request->name,
'description' =>$request->description
]);
return response()->json(['location'=>$location],200);
}
public function show($id)
{
$locations = Location::where('code','LIKE', "%$id%")->orWhere('name','LIKE', "%$id%")->orWhere('description', 'LIKE', "%$id%")->paginate();
return response()->json(['locations' => $locations],200);
}
public function update(Request $request, $id)
{
$location = Location::find($id);
$location->code = $request->code;
$location->name = $request->name;
$location->description = $request->description;
$location->save();
return response()->json(['location'=>$location], 200);
}
public function destroy($id)
{
$location = Location::where('id', $id)->delete();
return response()->json(['location'=>$location],200);
}
public function deleteAll(Request $request){
Location::whereIn('id', $request->locations)->delete();
return response()->json(['message', 'Records Deleted Successfully'], 200);
}
}
My route file:
api.php
<?php
use Illuminate\Http\Request;
Route::middleware('auth:api')->get('/user', function (Request $request) {
return $request->user();
});
Route::namespace('App\Sys\Http\Controllers')->group(function () {
Route::get('/menuslevel0',['uses' => 'MenuController#menus_level_0']);
Route::resource('locations','Api\LocationController');
});

Answer 1

You controller is in the App\Http\Controllers\Api, not in the App\Sys\Http\Controllers namespace. Remove the locations resource route in the namespace App\Sys\Http\Controllers group and create a new one.
Do this
...
Route::namespace('App\Sys\Http\Controllers')->group(function () {
Route::get('/menuslevel0',['uses' => 'MenuController#menus_level_0']);
});
Route::namespace('App\Http\Controllers')->group(function () {
Route::resource('locations','Api\LocationController');
});
...

Answer 2

Your controller is in App\Http\Controllers\Api and your route is pointing to App\Sys\Http\Controllers\Api.
You must change:
Route::namespace('App\Sys\Http\Controllers')->group(function () {
// Your routes
});
To:
Route::namespace('App\Http\Controllers')->group(function () {
// Your routes
});
