Steps to reproduce

1. Install a new Liferay instance
2. Install a Elasticsearch server (see: https://portal.liferay.dev/docs/7-2/deploy/-/knowledge_base/d/installing-elasticsearch )
3. Configure Liferay with REMOTE Elasticsearch configuration (see: https://portal.liferay.dev/docs/7-2/deploy/-/knowledge_base/d/configuring-the-liferay-elasticsearch-connector )
4. Execute a full reindex and verify search is working
5. Stop Liferay
6. Copy attached com.liferay.portal.search.elasticsearch6.xpack.security.internal.configuration.XPackSecurityConfiguration.config to LIFERAY_HOME/osgi/config folder
7. Start Liferay and check log files:
   • Expected behavior: NPE error in org.elasticsearch.node.InternalSettingsPreparer.replacePromptPlaceholders is not thrown
   • Wrong behavior: NPE error in org.elasticsearch.node.InternalSettingsPreparer.replacePromptPlaceholders is thrown
