Hey, I'm trying to setup the Elasticsearch server in the search-api drupal 8. But I'm getting the above message when I save the server. In parallel with that I accessed the Elasticsearch server URI in the postman, but it's giving the basic information about it(i.e version number, cluster name)? Can you help me with what's wrong with that? Thanks ---
