无法将对象类型消息发布到Mule 4中的消息队列(ActiveMQ)

我正在处理从3.9到4.1.4的Mule迁移,尝试将ArrayList转换为JSON,然后发布到JMS队列(使用ActiveMQ),得到下面的错误消息

代码:

<sub-flow name="xxxx_part_data_to_messaging_system_flow">
        <logger level="INFO" doc:name="Logger" doc:id="0607190d-f3ed-4b1b-a5b4-3572c08cf2d5" message='[vars.correlationId ++ "" ++ vars.batch_id]'/>
    <jms:publish doc:name="xxxx-part-data-jms-queue" doc:id="b44b1880-7374-4e4d-a0e0-1b4ab193ade4" config-ref="transactional_data_jms_connection_config" destination="${ld.transaction.xxxx.part.messaging.queue}">
    <jms:message >
    <jms:body ><![CDATA[#[[payload]]]]></jms:body>
    </jms:message>
    </jms:publish>
    <logger message="#[" $(vars.correlationId)-$(vars.batch_id) xxxx part posted successfully into transaction data queue ${ld.transaction.xxxx.part.messaging.queue}"]" level="INFO" doc:name="Logger" />
</sub-flow>

错误:

the data fetched from DB is ArrayList
