I think you are passing the wrong filter.

You should use a filter,

{"reviewInfo.reviewId":reviewId}

so your code will be like,

const reviewid  = req.params.product_id
reviewSchema.find({"reviewInfo.reviewId":reviewId}).then((value,err) => {console.log(value)})

in this query it just want to find an object exactly like this :

{reviewId:reviewid}

your query should be like this :

const reviewid  = req.params.product_id reviewSchema.find({'reviewInfo.reviewId':reviewid}}).then((value,err)
=> {console.log(value)})
