Serialize ArrayList using hypersistence-utils

Question

I have an issue when trying to save ArrayList of POJO to Postgres dataBase.

I followed the approach from https://vladmihalcea.com/how-to-map-json-collections-using-jpa-and-hibernate/ , but no luck.

This is sample pom:

        <dependency>
            <groupId>io.hypersistence</groupId>
            <artifactId>hypersistence-utils-hibernate-55</artifactId>
            <version>3.6.1</version>
        </dependency>

This is sample entity model:

@AllArgsConstructor
@Builder
@Getter
@Setter
public class History implements Serializable {
    @JsonSetter(nulls = Nulls.AS_EMPTY)
    private String topic;
    @JsonFormat(pattern = "yyyy-MM-dd HH:mm:ss")
    @JsonDeserialize(using = LocalDateTimeDeserializer.class)
    @JsonSerialize(using = LocalDateTimeSerializer.class)
    private LocalDateTime time;
}


@NoArgsConstructor
@AllArgsConstructor
@SuperBuilder
@Entity
@Getter
@Setter
@TypeDef(name = "json", typeClass = JsonType.class)
public class AccountingOperationJournal extends EntityObject {
    @Builder.Default
    @Column(length = 4000, columnDefinition = "jsonb")
    @Type(type = "json")
    private List<History> history = new ArrayList<>();
}

This is error:

Caused by: java.lang.IllegalArgumentException: The given string value: {"topic":null,"time":"2023-09-01 17:53:30"} cannot be transformed to Json object
    ... 125 more

The problem is that when there is only one value in the list, it is not serialized as an array. The string haven't got any []. I know that with jackson it is possible to fix by

@JsonFormat(with = JsonFormat.Feature.ACCEPT_SINGLE_VALUE_AS_ARRAY)

but I do not understand what I have to do with hypersistence
