Briefly, this error occurs when Elasticsearch detects an older trial license and automatically enables security features. This could cause issues if your applications aren’t configured to handle Elasticsearch’s security features. To resolve this, you can either configure your applications to work with Elasticsearch’s security features, or you can disable security in Elasticsearch by setting “xpack.security.enabled” to false in the elasticsearch.yml configuration file. Alternatively, you can upgrade your Elasticsearch license to a newer version that doesn’t automatically enable security.

if (isSecurityEnabled == true && isSecurityExplicitlyEnabled == false && mode == OperationMode.TRIAL && isSecurityEnabledByTrialVersion == false) { // Before 6.3; Trial licenses would default having security enabled. // If this license was generated before that version; then treat it as if security is explicitly enabled if (mostRecentTrialVersion == null || mostRecentTrialVersion.before(Version.V_6_3_0)) { logger.info("Automatically enabling security for older trial license ({})"; mostRecentTrialVersion == null ? "[pre 6.1.0]" : mostRecentTrialVersion.toString()); deprecationLogger.deprecated( "Automatically enabling security because the current trial license was generated before 6.3.0. " + "This behaviour will be removed in a future version of Elasticsearch. " + "Please set [{}] to true"; XPackSettings.SECURITY_ENABLED.getKey());
