getProfile(cb) {
  //let accessToken = localStorage.getItem("accessToken");;
  console.log("inside getprofile")
  let accessToken = this.getAccessToken();
  this.auth0.client.userInfo(accessToken, (err, profile) => {
    if (profile) {
      console.log("profile is ",profile)
      this.userProfile = profile;
    }
    //cb(err, profile);
    console.log("err is ",err)
  });
}
