我正在使用Nextjs创建一个Electron 商务应用程序.我有一个由对象组成的reviews数组，其中包含一个属性reviewBy.
我想像这样填充这reviewBy个属性:

因此，我编写了如下代码:
let product: any = await Product.findOne({ slug })
.populate({ path: "category", model: Category })
.populate({ path: "subCategories._id", model: SubCategory })
.populate({ path: "reviews.reviewBy", model: User })
.lean();
因此，根据我的指导老师的说法，他告诉我使用"reviews.reviewBy".但它在那个地方把我扔了null美元.
请帮帮我.因为我是新手.如果你觉得这个问题很愚蠢，请忽略它.这是个初学者的错误.:)
