Missing "presenceStatus" from Rest API plugin (.../v1/sessions)

Hello,

I am on Openfire 3.10.3 and using REST Api plugin (1.1.6).

I want to list all available sessions with call ...http://example.org:9090/plugins/restapi/v1/sessions

It works fine, except one thing, it is not returning "presenceStatus" in Json response, even in documentation this field is not marked as optional.

The same situation is with "node" response parameter. All other fields are returned, even "resource" which is optional.

Is there something which is affecting if "presenceStatus" is available in the response ? (some configuration, environment setup).

Or is just documentation wrong and it is not implemented at all ?

Thanks
