bug: openshell policy set returns UNIMPLEMENTED on server v0.0.13-dev

[tndejong]

Agent Diagnostic

Investigated via debug-openshell-cluster and openshell-cli skills. Confirmed:

• CLI version: v0.0.12 (installed via install.sh)
• Server version: v0.0.13-dev.8+gbbcaed2ea (ghcr.io/nvidia/openshell/cluster:dev)
• openshell policy get <sandbox> --full works (GetSandboxConfig RPC implemented)
• openshell policy list <sandbox> works (ListSandboxPolicies RPC implemented)
• openshell policy set <sandbox> --policy <file> --wait returns gRPC UNIMPLEMENTED
• OpenClaw's built-in policy approval UI can set policies successfully (version 2 shows Loaded), confirming the sandbox itself supports policy updates — the server-side gRPC handler for the policy set RPC is missing

Description

Actual behavior: openshell policy set returns status: Unimplemented, message: "" against a gateway running server v0.0.13-dev.8.

Expected behavior: openshell policy set should apply the updated policy YAML to the sandbox and return success.

Reproduction Steps

1. Install CLI v0.0.12 via curl -LsSf https://raw.githubusercontent.com/NVIDIA/OpenShell/main/install.sh | sh
2. Start gateway: openshell gateway start
3. Create a sandbox: openshell sandbox create --name test
4. Get current policy: openshell policy get test --full | awk '/^---/{found=1; next} found{print}' > /tmp/policy.yaml
5. Set policy: openshell policy set test --policy /tmp/policy.yaml --wait
6. Observe: Error: × status: Unimplemented, message: ""

Environment

• OS: macOS (darwin arm64)
• OpenShell CLI: v0.0.12
• Server: v0.0.13-dev.8+gbbcaed2ea (ghcr.io/nvidia/openshell/cluster:dev)

Logs

Error:   × status: Unimplemented, message: "", details: [], metadata: MetadataMap { headers: {"date": "Sat, 21 Mar 2026 17:04:14 GMT", "content-type": "application/grpc"} }

Thanks for reporting. 0.0.12 on mac is incorrectly pulling the 0.0.13 dev build which contains a breaking change. We'll cut a new 0.0.13 release to address the issue and get the CLI and Server aligned.

Try upgrading to the latest tagged 0.0.13 release now. This should address the issue by ensuring client and server RPCs match.

Please re-open if you continue to see issues. Thanks.
