django-allauth W001: ACCOUNT_LOGIN_METHODS conflicts with ACCOUNT_SIGNUP_FIELDS with Custom User Model (email as USERNAME_FIELD)

I'm working on a Django project using django-allauth and dj-rest-auth for authentication. I've set up a custom user model (CustomUser) where email is the USERNAME_FIELD and username is set to None. I'm consistently getting the following warning during system checks:

?: (account.W001) ACCOUNT_LOGIN_METHODS conflicts with ACCOUNT_SIGNUP_FIELDS 

Despite trying various configurations for ACCOUNT_LOGIN_METHODS and ACCOUNT_SIGNUP_FIELDS in my settings.py, this warning persists. My application seems to work (login/registration via email), but I'd like to resolve this warning to ensure my configuration is correct. Here are the relevant parts of my setup: models.py (users app):

from django.contrib.auth.models import AbstractUser 
from django.db import models
from .managers import CustomUserManager
class CustomUser(AbstractUser):
    username = None 
    email = models.EmailField(unique=True)

    is_active = models.BooleanField(default=True)
    is_staff = models.BooleanField(default=False)
    is_superuser = models.BooleanField(default=False)

    USERNAME_FIELD = 'email'
    REQUIRED_FIELDS = []
    objects = CustomUserManager()

    def __str__(self):
        return self.email

settings.py (relevant allauth/dj-rest-auth parts):

REST_FRAMEWORK = {

    'DEFAULT_AUTHENTICATION_CLASSES':(
        'rest_framework_simplejwt.authentication.JWTAuthentication',
        'dj_rest_auth.jwt_auth.JWTCookieAuthentication',
    )
}

# dj-rest-auth

# authentication Backend

AUTHENTICATION_BACKENDS = [
    'django.contrib.auth.backends.ModelBackend',
    'allauth.account.auth_backends.AuthenticationBackend',
]


ACCOUNT_USER_MODEL_USERNAME_FIELD = None
ACCOUNT_LOGIN_METHODS = {'email'}

ACCOUNT_SIGNUP_FIELDS = ['email','password']

ACCOUNT_EMAIL_VERIFICATION = 'none'

serializers.py:

from rest_framework import serializers
from .models import CustomUser


class RegisterSerializer(serializers.ModelSerializer):
    password = serializers.CharField(write_only=True)
    password2 = serializers.CharField(write_only=True, label="Confirm Password")

    class Meta:
        model = CustomUser
        fields = ['email', 'first_name', 'last_name','password', 'password2']

    def validate(self, attrs):
        if attrs['password'] != attrs['password2']:
            raise serializers.ValidationError({"password": "Your passwords didn't match."})
        return attrs
    
    def create(self, validated_data):
        validated_data.pop('password2')
        user = CustomUser.objects.create_user(**validated_data)
        return user

Django version 5.2.1, using settings 'fitcore.settings'
Starting development server at http://127.0.0.1:8000/
Quit the server with CONTROL-C.

Django: 5.2.1 Python: 3.12.x django-allauth: 65.8.1 dj-rest-auth: 7.0.1 What I've tried specifically for the W001 warning: ACCOUNT_SIGNUP_FIELDS = ['email'] ACCOUNT_SIGNUP_FIELDS = ['email', 'password'] Ensured ACCOUNT_USER_MODEL_USERNAME_FIELD = None and ACCOUNT_LOGIN_METHODS = ('email',) are set. Ensured deprecated allauth settings are removed.

My Questions:

1. Why am I still getting the W001 warning despite these configurations?
2. What is the definitive correct configuration for ACCOUNT_LOGIN_METHODS and ACCOUNT_SIGNUP_FIELDS when using email as the primary identifier (USERNAME_FIELD='email') and username = None?
3. Could my RegisterSerializer (used by dj-rest-auth) be somehow influencing allauth's interpretation of these settings, leading to the conflict?

Any insights or suggestions would be greatly appreciated!

Your signup fields has email as optional, Make it required by using "email*":

ACCOUNT_SIGNUP_FIELDS = ["email*", "password*"]

See this similar issue and the docs.
