Session Cookie ID blank after authorize call

Ran into a roadblock using the Sessions API. I’m trying to get the session cookie ID in order to use the /api/v1/sessions/me route to validate session data, however when we use the{clientId}&response_type=id_token&scope=openid&prompt=none&

authorization endpoint in our own backend to try and receive the cookie, the response’s sid field is blank, meaning we don’t have the cookie. However, when running the exact same call in Postman, the sid is present and everything is fine. I’m not sure about the proper way to get the session cookie information. Any information or guidance would be greatly appreciated.
