Problem/Motivation

Attempting to render a pdf on Drupal 11.2 throws the following error:

User notice: Drupal\Core\Render\Renderer::render with $is_root_call is deprecated in drupal:11.2.0 and is removed from drupal:12.0.0. Use Drupal\Core\Render\Renderer::renderRoot() instead. See https://www.drupal.org/node/3497318 → .

No PDF is generated.

Relevant change record: https://www.drupal.org/node/2511330 →

Steps to reproduce

Update to Drupal 11.2 and attempt to download a PDF with an existing link.

Proposed resolution

Update Drupal\entity_print\Renderer\RenderBase to use renderRoot instead of render():

/**
   * {@inheritdoc}
   */
  public function generateHtml(array $entities, array $render, $use_default_css, $optimize_css) {
    $rendered_css = $this->assetRenderer->render($entities, $use_default_css, $optimize_css);
    $render['#entity_print_css'] = $this->renderer->executeInRenderContext(new RenderContext(), function () use (&$rendered_css) {
      return $this->renderer->render($rendered_css);
    });

    $html = (string) $this->renderer->executeInRenderContext(new RenderContext(), function () use (&$render) {
//      return $this->renderer->render($render, TRUE);  OLD LINE.
      return $this->renderer->renderRoot($render); // NEW LINE.
    });

    // Allow other modules to alter the generated HTML.
    $this->dispatcher->dispatch(new PrintHtmlAlterEvent($html, $entities), PrintEvents::POST_RENDER);

    return $html;
  }
