据我所知。推送>>

foundCustomList.items.push（itemName）时出现此错误

这是模式定义

const listSchema = {
  name: String,
  items: [itemsSchema]
};

const List = mongoose.model("List", listSchema);

它正在使用itemsSchema

const itemsSchema = {
  name: String
};

const Item = mongoose.model("Item", itemsSchema);

请包含架构定义。您可以使用mongodb语法推送数据，
List.findOneAndUpdate（{name:listTitle}，{$push:{yourtItemArrayNamehere:itemName}}）。然后（data=>{}）。catch（err=>{}）
，如果您使用mongoose，在进行查询之前，您需要首先使用mongoose架构。请包含架构定义。您可以使用mongodb语法，
