[Python] 'RegisterSerializer' object has no attribute '_has_phone_field'

dj-rest-auth library has been returning this error when I send a request into the /registration endpoint

from rest_framework import serializers
from dj_rest_auth.registration.serializers import RegisterSerializer

class RegSerializer(RegisterSerializer):
phone = serializers.CharField(required = False)

def get_cleaned_data(self):
data= super().get_cleaned_data()
data['phone']=self.validated_data.get("phone","")
return data

Error message:


AttributeError at /auth/dj-rest-auth/registration/ 'RegisterSerializer' object has no attribute '_has_phone_field'

Error location:


C:\...\site-packages\allauth\account\adapter.py, line 338, in save_user

which points to this..

def save_user(self, request, user, form, commit=True):
from .utils import user_email, user_field, user_username

data = form.cleaned_data
first_name = data.get("first_name")
last_name = data.get("last_name")
email = data.get("email")
username = data.get("username")
user_email(user, email)
user_username(user, username)
if first_name:
user_field(user, "first_name", first_name)
if last_name:
user_field(user, "last_name", last_name)
if "password1" in data:
user.set_password(data["password1"])
elif "password" in data:
user.set_password(data["password"])
else:
user.set_unusable_password()
self.populate_username(request, user)
if commit:
user.save()
if form._has_phone_field:
phone = form.cleaned_data.get("phone")
if phone:
self.set_phone(user, phone, False)
return user



Tried to extend the RegisterSerializer that exists in the package, still didn't work, I followed the docs thoroughly but the issue persists, I don't see where the problem lies.
