Cannot translate paragraph entity (in entity_embed in ckeditor5)

Moving this to Drupal core, since it seems to be caused by an assumption in the content_translation module that every entity type must have a user reference field, either uid or content_translation_ui.

The Paragraph entity type, for instance, doe not have a user reference field and setting the author causes a problem, at least in this scenario.

Thanks for reporting,

Patches should actually be in MRs and may require test coverage as a bug.

Thanks for looking into this. I think something went wrong in the gitlab integration. I pushed a commit here https://git.drupalcode.org/issue/drupal-3519447/-/commit/84c5228d4507598... but it didn't detect it. I'll try an work on a test.
