I noticed when upgrading to D10.1 that I was getting this error:
PHP message: Uncaught PHP Exception TypeError: "node_menu_local_tasks_alter(): Argument #3 ($cacheability) must be of type RefinableCacheableDependencyInterface, Drupal\Core\Cache\CacheableMetadata given, called in /var/www/html/docroot/core/lib/Drupal/Core/Extension/ModuleHandler.php
I Identified that it was due to a missing use declaration of both the RefinableCacheableDependencyInterface and the CacheableMetadata classes.
Closed: works as designed
10.1 ✨
