Problem/Motivation

Error met,

The website encountered an unexpected error. Try again later.
TypeError: Drupal\Core\Render\Element::children(): Argument #1 ($elements) must be of type array, null given, called 
in /web/core/modules/layout_discovery/layout_discovery.module on line 45 in Drupal\Core\Render\Element::children() 
(line 72 of core/lib/Drupal/Core/Render/Element.php).

The corresponding code in modules/layout_discovery/layout_discovery.module is

  // Create an attributes variable for each region.
  foreach (Element::children($variables['content']) as $name) {
    if (!isset($variables['content'][$name]['#attributes'])) {
      $variables['content'][$name]['#attributes'] = [];
    }
    $variables['region_attributes'][$name] = new Attribute($variables['content'][$name]['#attributes']);
  }

    Don't see anything to review.

    But will need steps to reproduce this issue.

    Will also have to do some research about why that variable is empty, hopefully the steps help with that. Usually just putting an isset() could be masking a larger issue

    Agree with this principle. And the other part.

    Original code reinstalled. But the problem does not happen any where. Therefore not possible for me actually to get more information about the issue...

    This happens to me as well on 11.x-dev and the proposed solution seems to fix the problem

    I was kind of able to reproduce this by installing the Minimal profile, then applying a recipe that enabled gin + gin_toolbar + navigation (and imported config '*' from the navigation module).

    I am also running into this by installing the Minimal profile and then applying a recipe that enables gin + gin_toolbar + navigation and importing config '*' from the navigation module.

    Same setup here - minimal profile, recipe with gin etc. Until this morning, everything was fine. Then I noticed I'd been using the dev version of gin, so I upgraded to the RC. Immediately, my site was broken with the error in this issue. A search for the error brought me here. When I reverted back to the dev version of gin, the error was gone. Perhaps gin is the source of this?

    It has been close to a year with no further updates on this one, and most of the recent comments talk about incompatibility with Gin. I'm marking this one as closed.

    Please feel free to reopen or open a new issue if you can replicate this with just core.

    Thanks!
