这是mongoose模型的一部分

const mandateSchema = new mongoose.Schema({

基于给定的_id和eanID，我正在寻找一种方法来更新对象，该对象与新的status、end_date、stop_reason和可选的stop_note匹配，而不会丢失已经填充的start_date和eanID。
EnergyMandate.findByIdAndUpdate(energyMandateId的开始非常简单。但是对于更新部分，我不知道如何找到匹配的对象。我已经检查了Stackoverflow上的其他解决方案，但在我的示例中，首先是在tarias.gas和tarias.electricity之间进行拆分，然后搜索匹配的eanID。
