Laravel array key exists in get method

I am trying to fetch the the id and the name of the categories which is related to my services. A service has many categories and a categories belongs to a services. However when I try to get the id and the name as an array to return it gives me this error.

array_key_exists(): The first argument should be either a string or an integer.

Here is my method or function.

public function getCategories($idService)
{
    $service = Service::findOrFail($idService);
    return $service->categories->get(['id','name']);;
}

and here is the defined route.

Route::get('service/{service}/categories', 'ServiceController@getCategories');

I tried to look and browse for it but can't find any solution at all.

Use pluck() method instead 

return $service->categories->pluck('id','name');

The name of the parameter has to be equal to the wildcard and you need to use pluck() as mentioned in another comment, in your case:

public function getCategories($service)
{
    $service = Service::findOrFail($service);
    return $service->categories->pluck(['id','name']);
}

If service is a model you can also use eloquent:

public function getCategories(Service $service)
{
    return $service->categories->pluck(['id','name']);
}

i guess it related to with eager loading..need to use eager loading to fetch the relationship.. then use laravel collection if you want to filter more

public function getCategories($idService)
{
    return Service::with(['categories' => function ($query) {
         $query->select('id', 'name');
    }])->findOrFail($idService);
}
