I recently installed Nuxeo 5.9.5, and using its Document Management module. My application is using REST API to 'GET' the document details using documentById endpoint. It's working fine. However, when I want to see all the schemas, it is not getting retreived under 'properties'. I am seeing below error in the Nuxeo error log. Please suggest.
