Hello, i want to refresh this topic.

I pulled spring-data-opensearch repository. I run opensearch in docker. I configured properties to connect to my opensearch.

As for spring-boot-gradle (example) everything works great. README.md examples are working.
Unfortunately when I run spring-boot-java-client-gradle (example) and execute curl command from README.md, exception is thrown.

Servlet.service() for servlet [dispatcherServlet] in context with path [] threw exception [Request processing failed: org.springframework.dao.DataAccessResourceFailureException: Connection is closed] with root cause

Ah, this is sniffer’s fault, updated the examples here Exclude 'opensearch-rest-client-sniffer' from examples since Docker reports non-HTTPs address for container by default by reta · Pull Request #320 · opensearch-project/spring-data-opensearch · GitHub , thank you @dcwik
