WSO2 Iterate Mediator 为 WSO2 EI 中的每个迭代迭代相同的元素

Question

我正在使用 WSO2 迭代调解器将多条记录一一添加到 Salesforce ，并且来自 Salesforce 的所有响应都使用聚合进行聚合。 直到这工作正常。 Aggregation response contains multiple json Objects(each and everything is different element) , i need to fetch each json object elements and trace primary details(like Email,MobilePhone,LeadId,SF ErrorCode etc) to Database table. 为了实现这一点，我再次使用 Iterator 来拆分聚合响应。 对于每次迭代，它都会打印相同的 json 元素。 在这种情况下，有人可以帮我吗？

汇总响应：

笔记：

1. 聚合响应包含 3 个不同的 json 对象（请参阅：聚合响应）
2. 但迭代器内的脚本打印相同的 json 元素（即 dunleavy2010@hotmail.com）3 次（参见：日志详细信息）

请看一下并给我解决方案？
