java error when trying to fetch node from json response

BruceyBandit :

I am trying to retrieve details from a node within a json path using rest assured and java. However I keep getting the following error:

I know the issue is with this line in the code:

String token = jsonPathEvaluator.get("token");

How can this be fixed?

public void postAccessToken(){

    RestAssured.baseURI  = "https://xxx";

    JSONObject requestJsonBodyParams = new JSONObject();
    requestJsonBodyParams.put("test", "xxx");



    Response response = RestAssured.given()
            .contentType(jsonContentType).
                    body(requestJsonBodyParams.toString()).
                    when().
                    post("/");

    Assert.assertEquals(response.statusCode(), 200);

    JsonPath jsonPathEvaluator = response.jsonPath();
    String token = jsonPathEvaluator.get("token");
}

UPDATE:

Esha Singh :

I was facing the same error and after deep diving in POM.xml i figured out there were multiple groovy dependency however removing this :

Just worked like a charm. I am not sure if that would help but yes try removing multiples groovy dependency.
