<p>I have no clue what this means, and endless googling has not solved my case in anyway..</p>

<p>Here's the code that is probably relevant:</p>

<p><strong>views.py</strong></p>

<pre><code>class LoginView(views.APIView):
    def post(self, request, format=None):
        data = json.loads(request.body)

        email = data.get('email', None)
        password = data.get('password', None)

        account = authenticate(email=email, password=password)

        if account is not None:
            if account.is_active:
                login(request, account)

                serialized = AccountSerializer(account)

                return Response(serialized.data)
            else:
                return Response({
                    'status': 'Unauthorized',
                    'message': 'This account has been disabled.'
                }, status=status.HTTP_401_UNAUTHORIZED)
        else:
            return Response({
                'status': 'Unauthorized',
                'message': 'Username/password combination invalid.'
            }, status=status.HTTP_401_UNAUTHORIZED)
</code></pre>

<p><strong>serializer.py</strong></p>

<pre><code>class AccountSerializer(serializers.ModelSerializer):
    password = serializers.CharField(write_only=True, required=False)
    confirm_password = serializers.CharField(write_only=True, required=False)

    class Meta:
        model = Account
        fields = ('id', 'email', 'username', 'created_at', 'updated_at', 'full_name', 'password', 'confirm_password')
        read_only_fields = ('created_at', 'updated_at',)

        def create(self, validated_data):
            return Account.objects.create(**validated_data)

        def update(self, instance, validated_data):
            instance.username = validated_data.get('username', instance.username)

            instance.save()

            password = validated_data.get('password', None)
            confirm_password = validated_data.get('confirm_password', None)

            if password and confirm_password and password == confirm_password:
                instance.set_password(password)
                instance.save()

            update_session_auth_hash(self.context.get('request'), instance)

            return instance
</code></pre>

<p>This is occuring is because you are trying to access the data from <code>body</code></p>

<p>use -> <code>data = json.loads(request.data)</code></p>
