Unable to create custom fields

I’m trying to complete the knowledge graph final challenge and am getting an error when trying to create any custom fields: An unexpected error occurred while saving Field content.

Hi Erin,

This bug has been resolved, so you should now be able to save Custom Fields without issue.

Also, it seems like this error message was appearing when it shouldn’t have been, so if you look at Knowledge Graph > Configuration > Fields you should the fields that you created are appearing there!
