Я пытаюсь настроить приложение SaaS на основе Wagtail, используя django-tenants, чтобы иметь единую схему Postgres для каждого клиента.
Я строго установил django-арендаторов следуя документации ReadTheDocs, мне удалось успешно перенести схему publi c.
Однако, когда я добавляю первого клиента через Django Admin, миграция wagtailcore.0037_set_page_owner_editable завершается неудачно со следующей ошибкой:

Ниже вы можете найти код миграции Wagtail:
