Improperly configured at . error in Django REST framework

Question

When I access the base URL of http://127.0.0.1:8000/ I get the following error

ImproperlyConfigured at /
Could not resolve URL for hyperlinked relationship using view name "wallet-detail". You may have failed to include the related model in your API, or incorrectly configured the `lookup_field` attribute on this field.

When I try to access the admin URL it works fine but when I access my data URL which is http://127.0.0.1:8000/wallets I get a 404 error page not found?

This is my serializers.py file

from rest_framework import serializers

from .models import Wallet

class WalletSerializer(serializers.HyperlinkedModelSerializer):
    class Meta:
        model = Wallet
        fields = ('__all__')

My views.py file is the following

from django.shortcuts import render
from rest_framework import viewsets
from rest_framework.response import Response
from rest_framework.decorators import api_view
from .serializers import WalletSerializer
from .models import Wallet

@api_view(['GET'])
def getData(request):
    queryset = Wallet.objects.all()
    serializer = WalletSerializer(queryset, many=True, context={'request': request})
    return Response(serializer.data)

This is my Models.py file

from django.db import models

class Wallet(models.Model):
    raddress = models.CharField(max_length=60)
    def __str__(self):
        return self.raddress

I was using a simple class in my views.py file instead of 'GET' functions which I am doing now and I was also using routers in my urls.py file but I removed all that so I could create CRUD functions but I face this problem now
