Spring Integration MessageTransformationException无法转换消息

我正在尝试运行此（https://github.com/cloudfoundry-samples/wgrus/tree/master/spring-integration）使用spring集成v2.2.6.RELEASE的wgrus示例应用程序，并继续获取MessageTransformationException。该应用程序分为3个部分-商店UI，库存服务和运输服务（此处与该服务无关），并使用AMQP协议将消息发送到RabbitMQ。简而言之，您可以在UI中输入订单详细信息，然后以消息的形式将其发送到订单渠道。在后台，应用程序执行索赔检查，将消息存储在Mongo中（我可以看到它已存储）并返回一条新消息，其有效负载是所存储消息的ID-到目前为止，该消息已存储我可以看到amqpOut通道返回已存储消息的ID，即826bcbfb-21fa-424d-aecd-0bab3d1a690b-这可以在问题底部显示的调试中看到。下一个，消息通过出站AMQP通道发送到RabbitMQ，并且应该由清单服务接收，这时将引发异常。我可以看到，在调试打印时，存储的消息的ID有时会发生一些变化Payload=???sr?java.util.UUID????m?/

有没有人遇到过这个问题，并且知道如何解决？

商店用户界面使用的配置：

<int:object-to-json-transformer input-channel="orderChannel" output-channel="jsonOrders" content-type="text/x-json"/>

<int:claim-check-in input-channel="jsonOrders" output-channel="amqpOut" message-store="messageStore"/>

<amqp:outbound-channel-adapter id="amqpOut" amqp-template="rabbitTemplate" routing-key="orders"/>
...

库存服务使用的配置：

<int:claim-check-out message-store="messageStore" input-channel="orderChannel" output-channel="inventoryChannel" remove-message="true" />

<amqp:inbound-channel-adapter channel="orderChannel"
  connection-factory="rabbitConnectionFactory"
  queue-names="orders"
  error-channel="errorLogger" />

<int:logging-channel-adapter id="errorLogger" log-full-message="true" level="INFO"/>

<int:chain input-channel="inventoryChannel" output-channel="amqpOut">
  <int:json-to-object-transformer type="org.wgrus.Order"/>
  <int:enricher request-channel="creditCheck">
    <int:property name="approved" expression="payload.startsWith('OK')"/>
  </int:enricher>
  <int:enricher request-channel="inventoryRouter">
    <int:property name="reserved" expression="payload"/>
  </int:enricher>
  <int:object-to-json-transformer content-type="text/x-json" />
  <int:claim-check-in/>
</int:chain>
...
