应用错误收集

我在使用数据编辑转换消息时遇到问题，在mule 3.7中。输入XML的结构如下： input XML

错误如下：异常堆栈是： 1.不能强制a：string到a：array（com.mulesoft.weave.model.values.coercion.exception.UnsupportedTypeCoercionException） com.mulesoft.weave.model.values.formatting.ArrayFormatTypeCoercionValue：31（null） 2.执行时的例外情况： header_key：payload.data.header.Key， ^ 无法强制a：string到a：array（com.mulesoft.weave.mule.exception.WeaveExecutionException） com.mulesoft.weave.mule.WeaveMessageProcessor $ WeaveOutputHandler：162（null）
