  3. Fork the repository and make your change on a branch.
  4. Open a pull request that references the issue number.

Research direction

Reproduce the failure using the supplied pom.xml, application.yml, RestClientBuilderCustomizerImpl.java, Test entity, and DocRepository against Elasticsearch 8.17.2. Start by checking the configured URI and credentials alongside the custom REST client configuration, then verify the indices.exists request and its response. Done means the example connects successfully without the 401 or missing-response-body exception.
