Not getting response for the API

I have added below dependencies in my POM.xml file to automate API with RestAssured- rest-assured, json-path, json-schema-validator, xml-path and jackson-databind. But I am not getting response for the same. However, it's working fine in Postman. Below id my code-

package FirstAPIProject.firstAPIProject;
import static io.restassured.RestAssured.*;
import io.restassured.RestAssured;

public class Sample {

    public static void main(String[] args) {
        // TODO Auto-generated method stub
        RestAssured.baseURI="https://rahulshettyacademy.com";
        String response=given().queryParam("key", "qaclick123").headers("Content-Type", "application/json")
        .body("{\r\n" + 
                "  \"location\": {\r\n" + 
                "    \"lat\": -38.383494,\r\n" + 
                "    \"lng\": 33.427362\r\n" + 
                "  },\r\n" + 
                "  \"accuracy\": 50,\r\n" + 
                "  \"name\": \"Rahul Shetty Academy3\",\r\n" + 
                "  \"phone_number\": \"(+91) 983 893 3937\",\r\n" + 
                "  \"address\": \"29, side layout, cohen 09\",\r\n" + 
                "  \"types\": [\r\n" + 
                "    \"shoe park\",\r\n" + 
                "    \"shop\"\r\n" + 
                "  ],\r\n" + 
                "  \"website\": \"http://rahulshettyacademy.com\",\r\n" + 
                "  \"language\": \"French-IN\"\r\n" + 
                "}")
        .when().post("maps/api/place/add/json").then().assertThat().statusCode(200).toString();
        System.out.println(response);


    }

}

Output-

io.restassured.internal.ValidatableResponseImpl@4bd1f8dd
