Authentication credentials were not provided

[Afolabi Oluwapelumi]

I'm writing an api view for sign up for new users but postman is saying : 

{
    "detail": "Authentication credentials were not provided."
}

this is my view: class SignUpAPIView(CreateAPIView):

    serializer_class = SignUpSerializer
   
    def create(self, request, *args, **kwargs):
        serializer = self.get_serializer(data=request.data)
       
        if serializer.is_valid():
            user = serializer.save()
            return Response({'message': 'User registered successfully'}, status=status.HTTP_201_CREATED)
       
        return Response(serializer.errors, status=status.HTTP_400_BAD_REQUEST) 

          And serializer: 

class SignUpSerializer(serializers.ModelSerializer):
    email = serializers.EmailField(
        required=True,
        validators=[UniqueValidator(queryset=User.objects.all())]
    )
    password = serializers.CharField(write_only=True, required=True, style={'input_type': 'password'})
    confirm_password = serializers.CharField(write_only=True, required=True, style={'input_type': 'password'})

    class Meta:
        model = User
        fields = ['first_name', 'last_name', 'email', 'password', 'confirm_password']

    def validate(self, data):
        if data['password'] != data['confirm_password']:
            raise serializers.ValidationError("Passwords do not match.")
        return data

    def create(self, validated_data):
        validated_data.pop('confirm_password', None)
        return User.objects.create_user(**validated_data)                                                                

my settings.py: REST_FRAMEWORK = {

    "DEFAULT_AUTHENTICATION_CLASSES": [

        "rest_framework_simplejwt.authentication.JWTAuthentication",

        'rest_framework.authentication.BasicAuthentication',

        "rest_framework.authentication.SessionAuthentication",

    ],

    "DEFAULT_PERMISSION_CLASSES": [

        "rest_framework.permissions.IsAuthenticated"

    ],

ok, and? What is the problem ? Postman is saying exactly what is the problem. If you want to enable sign up without credentials you should override the permission classes for that endpoint with an empty list or with AllowAny

class SignUpAPIView(CreateAPIView):
    serializer_class = SignUpSerializer

    permission_classes = [AllowAny, ]

Next time please explain your question. And format the text to be easier to read. 

Also read the documentation and use google

https://www.django-rest-framework.org/api-guide/permissions/#allowany

Thank you very much, I actually thought I added that already. Thank you for the correction
