vcs_root_api.serve_property returns 406 for valid property names

[npaul3]

I'm trying to retrieve property values for vcs_roots like this:

vcs_root_location = root_id
scm_url = con.vcs_root_api.serve_property(vcs_root_locator,'url') # Also tried with 'username' and 'branch'

It always returns 406. Am I sending it in wrong format?

Complete stack trace:
