Briefly, this error occurs when Elasticsearch cannot find the security index, which is crucial for managing security features like user authentication and access control. This could be due to a new setup or a missing index. To resolve this, Elasticsearch attempts to create a new security index with an alias. If this error persists, you may need to manually create the security index, ensure that the Elasticsearch security feature is enabled, or check your Elasticsearch version as older versions may not support automatic creation of security indices.

This guide will help you check for common problems that cause the log ” security index does not exist. Creating [{}] with alias [{}] ” to appear. To understand the issues related to this log, read the explanation below about the following Elasticsearch concepts: plugin, index.

                assert indexState.concreteIndexName != null;
      "security index does not exist. Creating [{}] with alias [{}]"; indexState.concreteIndexName; this.aliasName);
                final byte[] mappingSource = mappingSourceSupplier.get();
                final Tuple mappingAndSettings = parseMappingAndSettingsFromTemplateBytes(mappingSource);
