Deserialization for list of objects is not working with Rest Assured Jsonpath and jdk8

Question

I have a Rest Endpoint that returns the below response

{
  "incentives": [
    {
      "incentiveId": "271230",
      "effectiveDate": "2022-06-01T07:00:00.000+0000",
      "expiryDate": "2022-10-01T03:00:00.000+0000",
      "incentiveName": "$500 MAZDA LOYALTY REWARD PROGRAM",
      "incentiveAmount": 500,
      "incentiveType": "discount",
      "disclaimer": ""
    },
    {
      "incentiveId": "271231",
      "effectiveDate": "2022-06-01T07:00:00.000+0000",
      "expiryDate": "2022-10-01T03:00:00.000+0000",
      "incentiveName": "$500 MAZDA MILITARY APPRECIATION BONUS CASH",
      "incentiveAmount": 500,
      "incentiveType": "discount",
      "disclaimer": ""
    },
    {
      "incentiveId": "271229",
      "effectiveDate": "2022-06-01T07:00:00.000+0000",
      "expiryDate": "2022-07-01T03:00:00.000+0000",
      "incentiveName": "MAZDA MOBILITY PROGRAM CASH BONUS",
      "incentiveAmount": 1000,
      "incentiveType": "discount",
      "disclaimer": "Program Period is 6/1/2022 - 6/30/2022."
    },
    {
      "incentiveId": "271242",
      "effectiveDate": "2022-06-01T07:00:00.000+0000",
      "expiryDate": "2022-07-06T06:59:00.000+0000",
      "incentiveName": "$500 MAZDA LEASE TO LEASE LOYALTY REWARD PROGRAM",
      "incentiveAmount": 500,
      "incentiveType": "discount",
      "disclaimer": ""
    }
  ]
}

I am using Rest Assured Jsonpath to deserialize the list of incentives using the below lines of code

JsonPath jsonPathEvaluator = response.jsonPath();
List<Incentive> incentivesList = jsonPathEvaluator.getList("incentives", Incentive.class);

But the above lines of code is throwing the following exception

Below are the dependencies in my pom.xml file

<!-- https://mvnrepository.com/artifact/io.rest-assured/rest-assured -->

Below is the java version on my machine

java version "1.8.0_333"
Java(TM) SE Runtime Environment (build 1.8.0_333-b02)
Java HotSpot(TM) Client VM (build 25.333-b02, mixed mode, sharing)

Could you please help me understand on what is wrong and on how to resolve this issue?

Could you show the class `Incentive`? Did you include `jackson-core` dependency in pom.xml? — lucas-nguyen-17, Jun 10 '22 at 03:20
@Srinivisan Ramu- Were you able to solve this issue? I'm facing the same issue. — Jagruuti, Sep 01 '22 at 10:11

My issue got solved by adding the below dependency in the pom.xml file, I'm using Java 11 version. The below dependency is used to support JDK8 data types.

<!-- https://mvnrepository.com/artifact/com.fasterxml.jackson.datatype/jackson-datatype-jdk8 -->
<dependency>
    <groupId>com.fasterxml.jackson.datatype</groupId>
    <artifactId>jackson-datatype-jdk8</artifactId>
    <version>2.13.3</version>
</dependency>
