unsupported

Error message

not implemented

What it means

The noop licensing API's Activate HTTP handler always returns an 'unsupported' error. This implementation exists so the service compiles/runs when no real licensing backend is wired in; every endpoint is a stub.

Solutions

1. Use a build that includes a real licensing provider (commercial build) if you need licensing
2. Return 404/ignore these endpoints in self-hosted deployments
3. Don't build automated flows against licensing endpoints when using the noop module

// client side: treat 4xx 'unsupported' from /license/activate as licensing-disabled
if resp.StatusCode >= 400 { log.Info("licensing not available in this build") }

When it happens

Trigger: Calling the license activation REST endpoint (POST to the licensing API) while the noop licensing module is registered instead of a real provider.

Common situations: Running the open-source/self-hosted build where licensing endpoints are intentionally disabled; hitting /license endpoints in local dev with the noop module loaded.
