User deprecated function: EntityDefinitionUpdateManagerInterface::applyUpdates()

On a fresh Drupal install core 8.7.4, with Content Translation enabled, after saving a new Entity I'm getting the following error:

User deprecated function: EntityDefinitionUpdateManagerInterface::applyUpdates() is deprecated in 8.7.0 and will be removed before Drupal 9.0.0. Use \Drupal\Core\Entity\EntityDefinitionUpdateManagerInterface::getChangeList() and execute each entity type and field storage update manually instead. See https://www.drupal.org/node/3034742. in Drupal\Core\Entity\EntityDefinitionUpdateManager->applyUpdates() (line 175 of core/lib/Drupal/Core/Entity/EntityDefinitionUpdateManager.php).

Steps to replicate:

1) Add Entity type, /admin/structure/eck
2) Just select Title as option.
3) Save.

The Entity type gets created and fields can be added as normal.

Not sure if the issue has something to do with this bug https://www.drupal.org/project/eck/issues/3055007 since on a fresh Drupal install and using composer to get the module, i don't see other errors but the one described above.
