[Vuejs]-I have error "local.ERROR: Class "App\Http\Controllers\Category" does not exist {"exception":"[object] (ReflectionException(code: -1):

You need to add use App\Models\Category; on top of controller.

Update, Next there is a type on Request as well, you need to update to:

 public function store(Request $request, Category $category)

you are using Reqeust instead.

Also, I am not sure, if there will $category on store case, because the model might only be supplied while updating.
