ODB Relationship не компилируется

У меня очень простая установка отношений, которую я не могу заставить выводить odb для компиляции, и это дает мне ошибку ниже компилятора. Я использую умные указатели Qt для реализации отношений, и мне всегда кажется, что я сталкиваюсь с одной и той же ошибкой, независимо от того, сколько перестановок я прохожу.

/usr/local/include/odb/database.ixx:570:54: error: no matching function for call to ‘odb::object_traits_impl<Inspection, (odb::database_id)1u>::find(odb::database&, const id_type&)’

вот родительский класс

#ifndef PART_H
#define PART_H

class Part;

#include <odb/core.hxx>
#include <odb/qt/lazy-ptr.hxx>
#include <QtCore/QString>
#include <QtCore/QByteArray>
