ALM_OCTANE_TECH_PREVIEW header issue

Can anyone confirm that they're able to use the ALM_OCTANE_TECH_PREVIEW header value with the API. I believe I'm passing this correctly in the headers, but the response is 403 error code.  I'm on the latest version (12.60.47.104) of Octane.

The simplified log below shows the authentication request, followed by another to the preview API.  I'm successful authenticating to Octane, and non-preview API requests work just fine.

[Debug] Connected to Octane: OK [Debug] ==================================== [Debug] Starting Signin Authorization: Basic XXXXXXXXXXXXX Accept: application/json ALM_OCTANE_TECH_PREVIEW: true [Debug] Response [Debug] ==================================== [Debug] OCTANE_USER Value is XXXXXXXXXXXXX [Debug] LWSSO_COOKIE_KEY Value is XXXXXXXXXXXXX [Debug] Starting Request [Debug] ==================================== Host: 192.168.2.158:8080 ALM_OCTANE_TECH_PREVIEW: true Set-Cookie: OCTANE_USER=XXXXXXXXXXXXX, LWSSO_COOKIE_KEY=XXXXXXXXXXXXX Accept: application/json

 

Any suggestions would be greatly appreciated.
