I'm trying to render or print my custom blocks on my node twig template and currently receiving a fatal error message.

Argument 1 passed to Drupal\block\BlockViewBuilder::view()

Here is the snippet of code I'm working on my .theme file

function iom_preprocess_node(&$variables) {

    $block = \Drupal\block\Entity\Block::load(917);
    $block_content = \Drupal::entityTypeManager()

$block returns NULL when I try to do a dump($block)

$block = \Drupal\block\Entity\Block::load(917);

Tried using twig tweak also to resolve the issue instead of having to pre-process it but no luck

{{ drupal_block('twitterfeed') }}

    Check if the variable $block returns NULL Oct 16, 2018 at 2:49
  • @AnishSheela just checked and yes it returned NULL. Checked the Block ID and it was correct

    It returned null means that there is an error loading that block. You need to check if block exists and corresponding module is enabled. Oct 16, 2018 at 6:16
  • enable block in any theme region ,once block rendered using code ,disable it not remove

You can print blocks directly using Twig Tweak

  {# No need to configure this block on "admin/structure/block" page. #}
  <dd>{{ drupal_block('system_branding_block', {label: 'Branding', use_site_name: false}) }}</dd>

  {# Bypass block.html.twig theming. #}
  <dt>Block (without wrapper):</dt>
  <dd>{{ drupal_block('system_branding_block', wrapper=false) }}</dd>

Source: Cheat sheet

Do not use the block's machine name, enable the devel and in block configuration click on Devel tab to get the Plugin ID.

For example, the Site Branding Block has machine name of sitebranding, but the plugin ID is system_branding_block

  • Tried this also using twig tweak to render the block on the node.html.twig template. Got an error that the block is missing {{ drupal_block('twitterfeed') }}. I have updated my question to provide some screenshots. Twig Tweak is installed by the way

  • @clestcruz updated the answer, most likely, you're using the wrong id.

Can you try this:

$bid = ?;
$block = \Drupal\block_content\Entity\BlockContent::load($bid);
$render = \Drupal::entityTypeManager()->getViewBuilder('block_content')->view($block);
return $render;
