Issue editing objects in CMS due to missing schema property

Hi there,
We are currently facing an issue in the CMS when we are not able to edit a particular object. We would get this log in the console.


Any help would be greatly appreciated. Thanks in advance!

Found the issue, it was because the schema was missing a

_type

property.

I also had the same error when making a schema change moving from an inline object to a declared schema type. Client complained that they couldn’t edit the items in the list. Had to delete the old ones. Not too hard, but painful that it failed so silently.
