Error while GET request for documentById using REST API

[Vinay_]

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.

[Florent_Guillau]

A few bugs around JSON generation have been fixed, please try with Nuxeo 6.0 which is being released at this moment and should be available shortly.
