Удостоверьтесь, что 'Letter.get (sendTransactionInstance.letter.id)' is not 'null' – Armaiti

Письмо в письмеTransaction nullable false .. LetterTransaction принадлежит букве, поэтому оно не может быть null –

Не зная причины, я исправил это, сохранив экземпляр письма после добавления letterTransaction вместо сохранения receiveTransaction .. это слишком странно.
