NextAuth.js Facebook provider

Question

How did you deal with "the email address cannot be returned for accounts created on mobile devices" using NextAuth.js Facebook provider

I need to store user email in DB

Answer 1

If user have not set an email address, email field value will be null in the response. I check the email this way:

  if (user.email === null) {
    throw new Error("Email address is required");
  }
