* Welcome! 👋 This is a great channel to share this. Thanks for identifying the issue and submitting the PR — that's really helpful! The Permit.io team monitors GitHub for SDK contributions, so your PR is in the right place. For ReBAC with Permit.io, once you get past this auth header issue, you can model relationships between resources. For example, you can set up resources, roles, and relations like this in Python:

await permit.api.resource_relations.create(
    "file",
    {
        "key": "parent",
        "name": "Parent",
        "subject_resource": "folder",
    }
)

(1) And assign resource-level roles:

await permit.api.role_assignments.assign(
    {
        "user": "<mailto:john@acme.com|john@acme.com>",
        "role": "viewer",
        "resource_instance": "file:2023_report",
    }
)

​*A quick note on Cloud PDP:*​ It's great for experimentation, but the documentation notes that for production deployments, the Docker Container PDP is recommended for better latency and availability. Also, the Cloud PDP is currently not compatible with ABAC or ReBAC policies. (2) , (3) So for your ReBAC POC, you'll likely want to run the container PDP locally:

docker pull permitio/pdp-v2:latest
docker run -it -p 7766:7000 --env PDP_DEBUG=True --env PDP_API_KEY=<YOUR_API_KEY> permitio/pdp-v2:latest

(2) To help our engineers investigate the 401 issue you encountered, could you share: 1. Which Workspace / Project / Environment you're using 2. The SDK calls you were performing (code snippet or cURL) 3. Which PDP version you were running 4. Any relevant logs from your PDP

We’ll also review your PR to make the SDK itself more RFC correct

Is it always recommended to use self-hosted container PDP for production?
