Django rest framework simple jwt: decode() got an unexpected keyword argument 'verify'-CodePudding

now I have this error from django rest framework, and I don't know why. All was fonctionnal before.

TypeError: decode() got an unexpected keyword argument 'verify'

I follow the simple dango rest simple jwt example.

My settings.py

REST_FRAMEWORK = {
    "DEFAULT_AUTHENTICATION_CLASSES": [
        "rest_framework_simplejwt.authentication.JWTAuthentication",
    ],
}

And my views.py

from rest_framework.views import APIView
from rest_framework.response import Response
from rest_framework.permissions import IsAuthenticated
from .models import User
from .serializers import UserSerializer, UserRegistrationSerializer
from django.http import Http404
from rest_framework import status
from django.views.decorators.csrf import csrf_exempt
from django.core.exceptions import ObjectDoesNotExist


class UserList(APIView):
    permission_classes = [IsAuthenticated]

    def get(self):
        users = User.objects.all().exclude(is_staff=True).order_by("id")
        serializer = UserSerializer(users, many=True)
        return Response(serializer.data)

    def post(self, request):
        serializer = UserRegistrationSerializer(data=request.data)
        if serializer.is_valid():
            serializer.save()
            return Response(serializer.data, status=status.HTTP_201_CREATED)
        return Response(serializer.errors, status=status.HTTP_400_BAD_REQUEST)


class UserDetail(APIView):
    permission_classes = [IsAuthenticated]

    @csrf_exempt
    def get_object(self, pk):
        try:
            return User.objects.get(pk=pk)
        except ObjectDoesNotExist:
            raise Http404

    @csrf_exempt
    def get(self, request, pk):
        user = self.get_object(pk=pk)
        serializer = UserSerializer(user)
        return Response(serializer.data)

    @csrf_exempt
    def put(self, request, pk):
        user = self.get_object(pk)
        serializer = UserSerializer(user, data=request.data, partial=True)
        if serializer.is_valid():
            serializer.save()
            return Response(serializer.data)
        return Response(serializer.errors, status=status.HTTP_400_BAD_REQUEST)

    @csrf_exempt
    def patch(self, request, pk):
        user = self.get_object(pk)
        serializer = UserSerializer(user, data=request.data, partial=True)
        if serializer.is_valid():
            serializer.save()
            return Response(serializer.data)
        return Response(serializer.errors, status=status.HTTP_400_BAD_REQUEST)

    @csrf_exempt
    def delete(self, request, pk):
        user = self.get_object(pk)
        user.delete()
        return Response(status=status.HTTP_204_NO_CONTENT)

I can generate the token with the route api/token but I can't use it after. Looks like the problem is straight from the django-rest-framework module or mybe my os with ssl problem. I am on linux mint.

Thanks for you help.

CodePudding user response：

The problem is in pyJWT version. Try to downgrade it to 2.0.1.

CodePudding user response：

Fixed the issue with PyJWT==2.1.0 and djangorestframework-simplejwt==4.8.0 in the requirements.txt:

PyJWT==2.1.0
djangorestframework-simplejwt==4.8.0

It may be noted that PyJWT 2.2.0 (Released: Oct 7, 2021) is causing the error. So pinning PyJWT<2.2 or alternatively PyJWT==2.1.0 in personal projects is a workaround for now, but ideally this would be either pinned appropriately here:

https://github.com/jazzband/djangorestframework-simplejwt/blob/master/setup.py#L59

or handled in source code.
