I have a spring boot project using azure cosmos db for nosql as the database, using CosmosRepository from spring-cloud-azure-starter-data-cosmos artifact. My entity looks like this:

import java.time.LocalDateTime;

import org.springframework.data.annotation.Id;

import com.azure.spring.data.cosmos.core.mapping.Container;
import com.azure.spring.data.cosmos.core.mapping.GeneratedValue;

import lombok.Data;

@Data
@Container
public class Post {
    @Id
    @GeneratedValue
    private String id;
    private String author;
    private String content;
    private String imageUrl;
    private LocalDateTime creationTime;
}

problem is, when persisting data, creationTime is for some reason stored as an array (example: "creationTime": [2024, 6, 16, 16, 51, 25, 571970017]), instead of an ISO string which I’d expect to be the default. This seemingly presents issues when using a repository method to sort posts by time (public List<Post> findAllByOrderByCreationTimeDesc();). Is there a way to specify that LocalDateTime be stored as an ISO string without changing creationTime to String and doing so manually?
