I'm stuck at the moment. Setup: I am eventually migrating to full Ory Network, but I am using self-hosted Oathkeeper+Keto. Right now, I am using Ory Network to manage the identities and sessions which is a

cookie_session

in my scenario. Problem: I am making an API request to get request a list of objects. In order to do this, I need to pass the

identity.id

from the session upstream to my backend API so I can use it to find the objects with the subject. When I log the headers in the backend api, I do not see the subject coming through. I'm kind of lost at this point and cannot find any help from the oathkeeper output logs. Code:

# Oathkeeper Config
authenticators:
      cookie_session:
        enabled: true
        config:
          check_session_url: <http://host.k3d.internal:4000/sessions/whoami>
          preserve_path: true
          extra_from: "@this"
          subject_from: "identity.id"
mutators:
      header:
        enabled: true
        config:
          headers:
            Subject: "Testing"
