I'm running into this issue where users are able to click the Publish button and publish Knowledge Articles successfully, but clicking on Revert to Draft throws an unhelpful error message.
The user has the permissions to create/read/write Knowledge Articles, as well as Approve/Publish. System Administrators are able to publish and unpublish successfully though so I assume that it must be an issue with another entity and not the Knowledge Articles.
Does anyone have any insight into this issue?
