It cannot auth with custom token auth class - python-3.x

Question

I tried to make custom auth class (DEFAULT_AUTHENTICATION_CLASSES), I want to auth with Bearer token. I could register an user, but I cannot login as an auth user.
I'm stuck. I used example and now I cannot get some info about auth token
authentication module
class BearerTokenAuthentication(BaseAuthentication):
keyword = 'Bearer'
def authenticate(self, request):
auth = get_authorization_header(request).split()
if not auth or auth[0].lower() != self.keyword.lower().encode():
return None
try:
access_token = auth[-1]
payload = jwt.decode(
access_token, settings.SECRET_KEY, algorithms=["HS256"]
)
except jwt.ExpiredSignatureError:
raise exceptions.AuthenticationFailed("The access token expired")
except IndexError:
raise exceptions.AuthenticationFailed("Bearer prefix missing")
return self.authenticate_credentials(payload["id"])
def authenticate_credentials(self, user_id: str):
try:
user = User.objects.get(id=user_id)
except User.DoesNotExist:
raise exceptions.AuthenticationFailed("Invalid token.")
return user, None
I guess I missed some settings because the auth variable is None. I wrote in the settings.py
REST_FRAMEWORK = {
'DEFAULT_PERMISSION_CLASSES': (
'rest_framework.permissions.DjangoModelPermissionsOrAnonReadOnly',
'rest_framework.permissions.IsAuthenticated',
),
'DEFAULT_AUTHENTICATION_CLASSES': (
'custom_authentication.authentication.BearerTokenAuthentication',
'rest_framework.authentication.SessionAuthentication',
),
}
AUTH_USER_MODEL = 'users.User'
serializer module
class LoginSerializer(serializers.ModelSerializer):
email = serializers.EmailField(max_length=255)
password = serializers.CharField(max_length=68, min_length=6, write_only=True)
confirm_password = serializers.CharField(write_only=True)
access = serializers.CharField(max_length=555, min_length=1, read_only=True)
refresh = serializers.CharField(max_length=555, min_length=1, read_only=True)
class Meta:
model = User
fields = ["id", "email", "password", "confirm_password", "access", "refresh"]
def validate(self, attrs):
email = attrs.get("email", "")
password = attrs.get("password", "")
confirm_password = attrs.get("confirm_password", "")
if password != confirm_password:
raise exceptions.ValidationError("Those password don't match")
validate_password(password)
user = auth.authenticate(email=email, password=password)
if not user:
raise AuthenticationFailed("Invalid credentials, try it again")
return {
"id": user.id,
"email": user.email,
"access": user.get_access().get("access"),
"refresh": user.get_refresh().get("refresh"),
}
Now I'm getting this "Invalid credentials, try it again". The user variable is None, too
