Issue

A page returns a 500 error because of a cached incorrect layout structure.

Steps to reproduce:

  1. Install 2.4-develop.

  2. Create and install custom module:
    1.1 Add a custom block to the catalog_category_view layout.
    1.1 Inject Magento\Framework\View\Result\Layout into the custom block through its constructor.

  3. Create the category shop.

  4. Open two terminal windows:

    1. Terminal 1: Continuously clean the layout cache:

      code language-shell 
      for i in {1..200}; do
  bin/magento cache:clean layout
done

    2. Terminal 2: Simulate concurrent requests to the category page:

      code language-shell 
      for i in {1..200}; do
  curl -s -o /dev/null -w "Request $i: HTTP %{http_code}\n""http://your_magento_base_url/shop.html?req=$i"
done

  5. Some requests randomly fail with a 500 status code, and the var/log/support_report.log shows the following error:

    code language-yaml 
    report.CRITICAL: The element with the "root" ID wasn't found. Verify the ID and try again. [] []

Expected results:

All requests return 200 OK.

Actual results:

Some requests intermittently return 500 Internal Server Error.
