Start at validateUserEditing in app/lib/server/functions/saveUser.js around line 210, then trace saveUserProfile in server/methods/saveUserProfile.js and the users.updateOwnBasicInfo endpoint in app/api/server/v1/users.js. Reproduce the Apple sign-in flow with missing email and fullName values; done means the account can register without the Cannot read property '0' of undefined error.
