Object of type CharField is not JSON serializable problem

Question

Creating my first CRUD in Django Rest framework this error keeps popping up. Does anyone know how to fix?? Object of type CharField is not JSON serializable

models:

class Pessoa(models.Model):
    id = models.AutoField(primary_key=True),
    nome = models.CharField(max_length=200),
    cpf = models.CharField(max_length=14, unique=True),

    def __str__(self):
        return self.nome

serializer:

class PessoaSerializer(serializers.ModelSerializer):
    class Meta:
        model = Pessoa
        fields = ('id', 'nome', 'cpf')

view(set):

class PessoaListCreate(generics.ListCreateAPIView):
    
    serializer_class = PessoaSerializer

    def get_queryset(self):
        queryset = Pessoa.objects.all()
        ocorrencia = self.request.query_params.get('ocorrencia')
        if ocorrencia is not None:
            queryset = queryset.filter(pessoa=ocorrencia)
        return queryset

The error message "Object of type CharField is not JSON serializable" typically indicates that Python is attempting to serialize an object that cannot be directly converted to JSON format. However, in the Django Rest Framework (DRF), CharFields should be serializable by default.

Try this changes:

# models.py

class Pessoa(models.Model):
    id = models.AutoField(primary_key=True)  # Removed comma
    nome = models.CharField(max_length=200)  # Removed comma
    cpf = models.CharField(max_length=14, unique=True)  # Removed comma

    def __str__(self):
        return self.nome

# serializer.py

class PessoaSerializer(serializers.ModelSerializer):
    class Meta:
        model = Pessoa
        fields = ('id', 'nome', 'cpf')

# views.py

class PessoaListCreate(generics.ListCreateAPIView):
    
    serializer_class = PessoaSerializer

    def get_queryset(self):
        queryset = Pessoa.objects.all()
        ocorrencia = self.request.query_params.get('ocorrencia')
        if ocorrencia is not None:
            queryset = queryset.filter(pessoa=ocorrencia)
        return queryset

python manage.py migrate
