While working with https://www.drupal.org/project/content_moderation → we encountered an error: InvalidArgumentException: Invalid translation language (es) specified. in Drupal\Core\Entity\ContentEntityBase->addTranslation() (line 958 of core/lib/Drupal/Core/Entity/ContentEntityBase.php).
The site has three languages EN, ES, PT
1. Create an EN node and keep it as Draft (Unpublished)
2. Create its ES translation and keep it as Draft (Unpublished)
3. Create its PT translation and keep it as Draft (Unpublished)
4. Publish its source language (EN)
5. Publish its ES translation
5. Delete PT translation
6. Edit the ES translation and create a new Draft (Unpublished) version
7. Added PT translation
At this point we can see the error.
We believe this is caused by https://www.drupal.org/project/drupal/issues/2860097 → .

Make sure the language we want to operate on won't be available in this version.
The language may have been removed in a version after this one.
1. Fixes should be in MRs

3. As a bug will need test coverage also
