Java 8 date/time type `java.time.Instant` not supported by default Issue : [duplicate]

Question

I am having a tough time understanding java.time.Instant library. I am not sure where there is not a straightforward solution way to implement Instant library. I have a spring-boot project where I have created RESTful service with CRUD operation on MongoDB. Everything was ok until I introduced Instant updatedOn & Instant createdOn in DTO.

Here sample code of my POST response where failure is occurring.

  @Override
  public ResponseEntity<ResponseDto> create(@RequestBody CLMDto CLMDto) {

    CLMDto createdCLMDto =
        CLMService.create(CLMDto);

    return ResponseEntity.status(HttpStatus.CREATED)
        .header(
            RESPONSE_HEADER_LOCATION, CLM_URL + "/" + createdCLMDto.getId())
        .body(ResponseDto.builder().value(createdCLMDto).build()); //--------------------->**Failing here**
  }

My response DTO looks something like this

@Data
@Builder
@JsonInclude(JsonInclude.Include.NON_DEFAULT)
public class ResponseDto {

  private Integer count;
  private Object value;
  private Object error;
  private Object info;
}

and CLMDto

@Data
@Builder
@NoArgsConstructor
@AllArgsConstructor
public class AdminDataDto {
  
  private Instant createdOn;
  private Instant updatedOn;
  @JsonProperty(value = "updatedByName", access = JsonProperty.Access.READ_ONLY)
  private String updatedByName;
}

In debugger, i noticed place where exception is happening variable createdCLMDto has following values

createdOn:Instant@193 "2021-03-27T11:53:24.774765300Z"
updatedByName:test
updatedOn:Instant@195 "2021-03-27T11:53:24.774765300Z"

as I am using Lombok plugins so I can't debug inside and find the root cause on autogenerated code. I am not looking for a solution but a suggestion where things can go wrong here. My exact error is

  Type definition error: [simple type, class java.time.Instant]; nested exception is com.fasterxml.jackson.databind.exc.InvalidDefinitionException: 
Java 8 date/time type `java.time.Instant` not supported by default: add Module \"com.fasterxml.jackson.datatype:jackson-datatype-jsr310\" to enable 
handling (through reference chain: 
com.abc.service.dto.ResponseDto[\"value\"]->com.abc.dto.AdminDataDto[\"createdOn\"])",

Needless to say but I already tried the solution provided here to updated maven libraries but no success. I find many questions on StackOverflow around this library but no one is explaining the easiest way to implement this libarary.

I have already following dependency in pom.xml

        <dependency>
            <groupId>com.fasterxml.jackson.datatype</groupId>
            <artifactId>jackson-datatype-jsr310</artifactId>
        </dependency>

I have already tried the solution provided here Java 8 date time types serialized as object with Spring Boot
