Describe the issue:
I am calling the and index search using RestClient like below code
package dev_test;
import org.springframework.http.HttpHeaders;
import org.springframework.http.HttpMethod;
import org.springframework.http.MediaType;
import org.springframework.web.client.RestClient;
import java.util.Base64;
import java.util.Map;
public class TestRestClient {
public static void main(String[] args) {
String baseUrl = "http://localhost:5601/"; // 🔁 Replace with your base URL
RestClient restClient = RestClient.builder()
.baseUrl(baseUrl)
.defaultHeader(HttpHeaders.CONTENT_TYPE, MediaType.APPLICATION_JSON_VALUE)
.defaultHeader(HttpHeaders.AUTHORIZATION, "Basic "
+ new String(
Base64.getEncoder()
.encode(("admin" + ":" + "Password@123").getBytes())))
.build();
Map<String, Object> requestBody = Map.of(
"size", 100
);
try {
String response = restClient.method(HttpMethod.GET)
.uri("example_index/_search")
.body(requestBody)
.retrieve()
.body(String.class);
System.out.println("✅ Response: " + response);
} catch (Exception e) {
System.err.println("❌ Error: " + e.getMessage());
}
}
}

Error: 404 Not Found: “{“statusCode”:404,“error”:“Not Found”,“message”:“Not Found”}”
But using same restclient if i call findings API

Please any one find or help with issue.
