Briefly, this error occurs when an anonymous user tries to perform an action on Elasticsearch but doesn’t have the necessary permissions. This is often due to incorrect or insufficient security settings. To resolve this issue, you can either provide the necessary permissions to the anonymous user or disable anonymous access and ensure that all users are authenticated before they can perform any actions. Alternatively, you can also check your Elasticsearch configuration to ensure that the security settings are correctly configured.

                            localNodeInfo.prefix; originAttributes(threadContext; message; localNodeInfo); action;
                            arrayToCommaDelimitedString(indices.get()); message.getClass().getSimpleName(); opaqueId());
                } else {
                    logger.info("{}[transport] [anonymous_access_denied]\t{}; action=[{}]; request=[{}]{}"; localNodeInfo.prefix;
                            originAttributes(threadContext; message; localNodeInfo); action; message.getClass().getSimpleName();
                            opaqueId());
