Drupal throws a 500 error for any 4xx exception(e.g. 404) with the following log message:
TypeError: metatag_generate_entity_all_tags(): Argument #1 ($entity) must be of type Drupal\Core\Entity\ContentEntityInterface, null given, called in /var/www/html/web/modules/contrib/metatag/metatag.module on line 634 in metatag_generate_entity_all_tags() (line 646 of /var/www/html/web/modules/contrib/metatag/metatag.module).Note: This only happens when custom error pages are not set.
1. Created a new Gitpod with 1.x-dev with Drupal 10 & Nuxt 3 (latest, recommended)
2. Navigated to /ce-api/node/some404page
3. "The website encountered an unexpected error. Please try again later."
4. Checked logs
Fixed
2.0
Code
That is because it tries to get the page node and there is none.
I made this patch to make it work for me.
