问题描述
我几个月来一直在追查这个错误，但无法确定它的来源。我有一个发送电子邮件地址的故障序列（不是我写的）。相关部分是（我认为）：
<property name="Subject" scope="transport" type="STRING" value="WSO2 Error Report"/>
<property name="MessageType" scope="axis2" type="STRING" value="text/html"/>
<property name="ContentType" scope="axis2" type="STRING" value="text/html"/>
<header expression="concat('mailto:','[email protected],[email protected]')" name="To" scope="default"/>
<property name="FORCE_CONTENT_TYPE_BASED_FORMATTER" scope="axis2" type="STRING" value="true"/>
<property name="FORCE_SC_ACCEPTED" scope="axis2" type="STRING" value="true"/>
<property name="OUT_ONLY" scope="default" type="STRING" value="true"/>
<call>
<endpoint>
<default/>
</endpoint>
</call>
这是我唯一可以发送两个电子邮件地址的地方。触发此序列时，我会在 Kibana 日志中看到此错误：
Message :: = 发生意外错误，:: ERROR_MESSAGE :: = 目标地址无效：[email protected],[email protected]/，:: ERROR_CODE :: = 401003
我知道错误是什么......它是尾随正斜杠，但我不知道它来自哪里。我对 WSO2 序列的了解不够，不知道去哪里找。正斜杠不在 XML 文件中，但在发送电子邮件之前，我应该在哪里查看电子邮件的格式？似乎那将在“默认”端点中，但我不知道那是什么，即使在阅读了 WSO2 ESB 文档之后也是如此。
运行 6.6.0 的 EI。
