"InvalidArgumentException: Field field_media_images is unknown. in Drupal\Core\Entity\ContentEntityBase->getTranslatedField()" When trying to add an existing field to a new content type

This may happen when some code calls something like :

$entity->get($field)

with a field that is not present on given entity.

Closing this issue as no steps to reproduce were ever provided, and it seems something is going wrong rather than being broken.

If anyone is able to reproduce the issue on a fresh install, please create a new issue with clear steps to reproduce, starting with 'Install Drupal'.

we get this error on get() methods. we need to check the field exists with isset() before we use the get() method.
