Why are you dont use remoteScript?

[codegor]

class FieldServiceProvider extends ServiceProvider
{
   /**
     * Bootstrap any application services.
     *
     * @return void
     */
    public function boot()
    {
       ...
       Nova::serving(function (ServingNova $event) {
            Nova::script('google-autocomplete', __DIR__.'/../dist/js/field.js');
            Nova::style('google-autocomplete', __DIR__.'/../dist/css/field.css');
            Nova::remoteScript('https://maps.googleapis.com/maps/api/js?key='.config('google-autocomplete.api_key').'&libraries=places');
            Nova::provideToScript([
                'google_autocomplete_translations' => $this->getTranslations(),
            ]);
        });
    }
   .....
}
