14. 409 - addon already enabled

The request tried to enable an addon that is already enabled for this tenant. The endpoint is intentionally not idempotent - it returns 409 so the caller knows the state didn't change.

Re-enabling an addon that's already on.

curl -X POST "https://$OC_HOST/v1/tenants/$OC_TENANT/addons" \
  -H "Authorization: Bearer $OC_TOKEN" \
  -H "Content-Type: application/json" \
  -d '{"addon": "ask"}'

{
  "error": "addon_already_enabled",
  "message": "addon 'ask' is already enabled for this tenant",
  "retry": false
}

• Check the current state first: GET /v1/tenants/:t/addons returns the list of enabled addons.
• If your script is meant to be idempotent, treat this 409 as a no-op success.
• If you wanted a different addon, fix the body and retry with the right code.
• retry: false - the state is already what you wanted.
