After upgrade to 2.3.0 ES (including Graph plugin installation), we get following reponse for any Graph API request
{ "error": { "root_cause": [ { "type": "security_exception", "reason": "current license is non-compliant for [graph]", "license.expired.feature": "graph" } ], "type": "security_exception", "reason": "current license is non-compliant for [graph]", "license.expired.feature": "graph" }, "status": 401 }
That's probably because we have basic licence received to use Marvel plugin for free.
I don't know how to get/create/request trial license for Graph plugin to add it manually
Thanks,
