Getting 500 Internal Server Error status when executing the GET ID via RestAssured class whereas received 200 status when tried on Swagger tool - rest-assured

Question

Swagger - screenshot2 Swagger - screenshot1I'm practicing how to perform GET ID request in RestAssured on sample working API.
When I run the GET request on swagger tool manually I am receiving the expected api response with status code as 200 but when I tried through RestAssured scripts (in BDD format) it throw status code as 500 continuously.
Posting my scripts and error shown in the console below. Please help me to find out the issue.
Note: I can able to successfully run RestAssured for one of the POST service for record creation.
package RestfulApiDemo;
import io.restassured.RestAssured;
import io.restassured.http.ContentType;
import io.restassured.response.Response;
import io.restassured.response.ValidatableResponse;
import io.restassured.specification.RequestSpecification;
public class GetRecord {
public static void main(String[] args) {
RestAssured
.given()
.log().all()
.baseUri("http://localhost:8080/app/")
.basePath("videogames/{videoGameId}")
.pathParam("videoGameId",1)
.contentType(ContentType.JSON)
.when()
.get()
.then()
.log().all()
.statusCode(200);
}
}
Error seen in console

Answer 1

I think you missed the part .accept(ContentType.JSON)
RestAssured
.given()
.log().all()
.baseUri("http://localhost:8080/app/")
.basePath("videogames/{videoGameId}")
.pathParam("videoGameId", 1)
.accept(ContentType.JSON)
.when()
.get()
.then()
.log().all()
.statusCode(200);
