如果从wso2dss传递了一个数据库列值（如潜在客户机），则esb开始在esb控制台中抛出此错误

如何避免此错误，以便有效负载能够读取包含的值并给出成功响应

消息格式化程序和生成器：

<messageFormatter contentType="application/json"
                          class="org.apache.axis2.json.JSONMessageFormatter"/>

        <messageFormatter contentType="application/json/badgerfish"
                          class="org.apache.axis2.json.JSONBadgerfishMessageFormatter"/>

<messageBuilder contentType="application/json"
                        class="org.apache.axis2.json.JSONBuilder"/>

通过stacktrace，我看到异常是在序列中的PayloadFactory元素中引发的。你能把它和你的问题一起发布吗？嗨，Philippe，是的，这是从Payload mediator得到的。我不知道为什么，我已经用代理和它的序列编辑了我的问题，供你参考。代码有效吗？我也有类似的例外。
