System cron not running properly

Hi.

I'm looking into running drush elysia-cron run though when it comes to the system_cron

Cron job system_cron started.
WD cron: Exception: exception 'EntityMalformedException' with message 'Missing bundle property on entity of type file.' in                                           [error]

Cron job system_cron ended in 0 secs.

Drush is outside the docroot, I only removed the directories for simplicity.
The same message is also found on dblog between the system cron run.
I only have update manager disabled and feeds scheduled to run every once in an hour.

Thanks
