我正在新的 Mule 运行时 4 上移动流，但我对 MongoDB 连接器版本 5 有问题。在第一个连接工作正常之后，从第二个连接开始，它会抛出错误：

有人可以提示正在发生的事情吗？我真的被困住了。
由于它收集了文档，我认为它被挂起了集合中的下一个对象。
你能尝试使用
<mongo:find-documents>
代替
and let me now if it works..
好的，我已经想通了。mongo 查询(位于标签 <mongo:find-query>{"Process":true}</mongo:find-query> 之间(无法解析 mongo 形状。在 mongo 形状之前将其放入转换中，解决问题
