After promoting an instance from 6.5 community to 6.5 Enterprise then up to latest 7.x all users except for System Administrators can't access records. I have tracked logs and JS errors to the issue that no records have a team assigned to them. When I attempt to mass update (Or Update via Record Detail) the dropdown does not render. This is due to a JS exception "Uncaught RangeError: Maximum call stack size exceeded". This is causing issues. I have also seen multiple repeated log entries for Metadata file creation failure and unserialize failures (Huge amounts of these during a Elasticsearch reindex.) I confirm ES is opperational and reachable.
