How can I display the field of the current page in a block twig template

In my Basic page content type I have an image field called sidebar_image.

I have placed a block to my header region called header_block which is using a custom twig template. I'm wondering how I can get the Basic page sidebar_image to be displayed in my header_block twig template:

<h1>Some header</h1>
<img src="{{ sidebar_image }}" />

and in the preprocess function:

THEME_preprocess_block__header_block {
  $variables['sidebar_image'] = // get current pages sidebar image URL
}

You should be able to load current page (node) like this:

$node = \Drupal::routeMatch()->getParameter('node');
if ($node instanceof \Drupal\node\NodeInterface) {
  // You can get nid and anything else you need from the node object.
  $nid = $node->id();
}

And then should be possible to access field value like:

$node->get('field_sidebar_image')->getValue();

Just add some checking if your node is in specific content type and similar.
