ContainerAwareTrait" not found in Drupal 11

Just came across this same issue when migrating my Drupal site to Drupal 11.

The issue stems from upgrading Symfony from 6.4 to 7.1. In Symfony 6.4, ContainerAwareTrait became deprecated, with Symfony 7.1 being removed.

See Drupal change note that addresses this issue for the module maintainers. CallableResolver and ClassResolver no longer support ContainerAwareInterface →
