Fetch directory doesn't work

> Resources Endpoints > Directory > PUT

Fill the form:
-directoryName: subject

• entryID:(existing entry id)

Click on Fetch Directory entries

==> Error:

{"entity-type":"exception","status":404,"message":"com.sun.jersey.api.NotFoundException: null for uri: http://localhost:8080/nuxeo/site/api/v1//directory/subject/test"}

Expected: Fill the textarea with the JSON entry of the directory value.

Note that we get the same error when trying to fetch a document on ID and path endoints.
