i'm tring build rest api using django-rest-framework , python 3.6, facing issue post requests

i can post json data using postman endpoint content-type set "application/json" , read dict doing request.data. works if start server running

python manage.py runserver 

however, when i'm debugging on visual studio code , django's standard httprequest object not overridden django-rest-framework's enhanced request object , raises rawpostdataexception("you cannot access body after reading request's data stream")
