Undefined index: email with fosuserbundle - symfony

Question

I have an existing app installed from git repo and know he should work, but having problems with launching it. App uses fosuserbundle
and I'm getting following error on both login/sign up:
Undefined index: email in /var/www/relabld-old/website/vendor /doctrine/orm/lib/Doctrine/ORM/Persisters/Entity/BasicEntityPersister.php on line 1704
although email field exists in my User class:
use FOS\UserBundle\Model\User as BaseUser;
use Doctrine\ORM\Mapping as ORM;
use Doctrine\ORM\Mapping\Index;
use Doctrine\Common\Collections\ArrayCollection as ArrayCollection;
use Symfony\Bridge\Doctrine\Validator\Constraints\UniqueEntity;
use Symfony\Component\Validator\Mapping\ClassMetadata;
use Symfony\Component\Validator\Constraints as Assert;
use Relabld\CommonBundle\Entity\UserStatus;
use Symfony\Component\Form\Extension\Core\ChoiceList\SimpleChoiceList;
use Doctrine\Common\Collections\Criteria;
use Relabld\CommonBundle\Entity\ItemStatus;
use Relabld\CommonBundle\Validator\Constraints as CustomAssert;
/**
* #ORM\Entity(repositoryClass="Relabld\CommonBundle\Entity\UserRepository")
* #ORM\Table(name="fos_user", indexes={#ORM\Index(name="first_name_idx", columns={"firstName"}), #ORM\Index(name="last_name_idx", columns={"lastName"}) , #ORM\Index(name="full_name_idx", columns={"fullName"})} )
* #UniqueEntity(fields={"email"}, groups={"Registration","Basics"}, message="Email is already used")
* #UniqueEntity(fields={"username"}, groups={"Registration"})
* #ORM\HasLifecycleCallbacks
* #CustomAssert\CustomUser
*/
class User extends BaseUser
{
/**
* #ORM\Id
* #ORM\Column(type="integer")
* #ORM\GeneratedValue(strategy="AUTO")
*/
protected $id;
/**
* #var string
* #Assert\Email(
* message = "The email '{{ value }}' is not a valid email.",
* groups={"requestInvitation"}
* )
*/
protected $email;
...
What could be the reason of this?

Delete email field, this field already exists.
