Thanks Bryan, I posted it in the Isilon community as well. I did figure out the problem: a bad formatted GET request. It looks like the namespace service is too sensitive to a null body. My original playbook was: headers:Cookie: "isisessid={ { results_login.cookies.isisessid }}"X-CSRF-Token: "{ { results_login.cookies.isicsrf }}"x-isi-ifs-target-type: "container"referer: "{ { Isilon_IP }}"body_format: json The last line is not actually needed because I'm not sending anything in the GET body, I removed it and it is now working as expected. The 'platform' service is not as sensitive, the GET there still hast the NULL body and it still works.
Can anyone provide a working example of the syntax to access the 'namespace' service ? I'm using Ansible uri module with session cookies. I know the module works because I can get the sessionID and use it to get 'platform' queries successfully, but when I try to do the same for the 'namespace' service, it doesn't work. A regular curl/get command does get me a reply from the both services so I suspect is something I'm missing in my ansible playbook. I do understand that I need to create 'namespaces' but the default /ifs is there and accessible by root and I can't even query that one. This is the syntax I'm using (it's exactly the same as the one I use for the 'platform' service).
