  • You have to pass `{new: true}` to `findOneAndUpdate` method to get in return modified document. Check this answer it will help you. https://stackoverflow.com/questions/32811510/mongoose-findoneandupdate-doesnt-return-updated-document – Waseem Ansar Dec 12 '19 at 05:54
  • `findEmail` is not returning anything. – Ashh Dec 12 '19 at 06:03
  • User.findOneAndUpdate is asynchronous function in mongoose either you have to pass call back to findEmail function or use async/await for functions. – PrasathBV Dec 12 '19 at 10:15
