Как импортировать swagger/?format=openapi в postman из django-rest-swagger без ошибки format not recognized?

Наш проект использует django-rest-swagger для управления API, и мы хотели бы экспортировать все api и импортировать Postman, Я могу получить JSON по нижеприведенному url localhost:5000/swagger/?format=openapi, но когда я импортирую файл, postman говорит Error while importing: format not recognized, Как импортировать swagger/?format=openapi в postman из django-rest-swagger без ошибки не распознанного формата?

Есть ли кто-нибудь, кто знает какой-нибудь простой способ решить эту проблему? Большое спасибо за любой совет.
