When my site contains nodes using content moderation and I run a full content export ($ drush dcdes) I get content exported to files in the node and content_moderation_state folders. If I delete a node that uses content moderation and try to import ($ drush dcdi) I get the following error:
[error] Error: Attempt to assign property "moderation_state" on null in Drupal\content_moderation\Entity\ContentModerationState->save() (line 165 of /var/www/html/core/modules/content_moderation/src/Entity/ContentModerationState.php)
This error also happens if I export my content again after deleting the node using content moderation, then import.
We need a way to remove the content_moderation_state files after an associated node is deleted. Or maybe a drush command to remove all content JSON files before performing an export to ensure there aren't any entities remaining that point to non-existent nodes.

Not all content is available!
It's likely this issue predates Contrib.social: some issue and comment data are missing.
I got this error even with the force option checked. I was able to work around it by moving the content_moderation_state directory away, doing an import, putting that directory back in place, and running the update again.
I have the same issue as @liam morland
about to test the workaround which is to move the content_moderation_state directory away during the first import and putting it back for another import.
