Email not returning from user profile

API
3

Thanks!, I fixed it - had it in

"id_token": {
    "email": null,
    "email_verified": null
  },
  "userinfo": {
    "picture": null
  }

instead of

"userinfo": {
    "picture": null,
    "email": null
  }

Regarding the other fields there (e.g. aud, azp, exp), are any one of them a unique ID I can refer to the user as?
