I am trying to generate html output of whole page and then pass it to response array.I am doing something like this:

  $page = array(
  '#theme' => 'html',
  '#page_object' => render($content),
   );

$content is a render array. I am passing render($page) to the response object, but I am getting error this error:

LogicException: A stray drupal_render() invocation with $is_root_call = TRUE is causing bubbling of attached assets to break. in Drupal\Core\Render\Renderer->doRender() (line 377 of core\lib\Drupal\Core\Render\Renderer.php).

What should I do to make this correct? Thanks

I am trying to generate html output of whole page and then pass it to response array.I am doing something like this:

  $page = array(
  '#theme' => 'html',
  '#page_object' => new HtmlPage(render($content)),
   );

$content is a render array and new HtmlPage creates a HtmlPage object from an existing page. I am passing render($page) to the response object, but I am getting error this error:

LogicException: A stray drupal_render() invocation with $is_root_call = TRUE is causing bubbling of attached assets to break. in Drupal\Core\Render\Renderer->doRender() (line 377 of core\lib\Drupal\Core\Render\Renderer.php).

I am trying to generate html output of whole page and then pass it to response array.I am doing something like this: $page = array( '#theme' => 'html', '#page_object' => render($content), );

here $content is a render array representing themed output of content.And then I am finally passing this render($page) to Response object. But I am getting error this error:

LogicException: A stray drupal_render() invocation with $is_root_call = TRUE is causing bubbling of attached assets to break. in Drupal\Core\Render\Renderer->doRender() (line 377 of core\lib\Drupal\Core\Render\Renderer.php).
