[Help Needed] TypeError: UserType fields cannot be resolved on a custom user model

[ash-lyrid]

I am trying to use this package, coming from django graphene auth background.

I am getting the following error - TypeError: UserType fields cannot be resolved. GraphQL type for model field 'users.User.email' has not been implemented

GqlAuthSettings

I think there is no straight forward way to add the email type to the user type as I am using a custom email field. I can see there is a TODO item to support custom UserType implementation. I will wait till that is implemented as I am unable to use this package for the time being. Please correct me if there is an alternative way to resolve this. Thanks.

what's your email_field?

[ash-lyrid]

from gqlauth.settings_type import GqlAuthSettings, password_field, email_field I am using email_field from gqlauth only

This is my custom email field.

class LowercaseEmailField(models.EmailField):
    """
    Override EmailField to convert emails to lowercase before saving.
    """
    def to_python(self, value):
        """
        Convert email to lowercase.
        """
        value = super(LowercaseEmailField, self).to_python(value)
        # Value can be None so check that it's a string before lowercasing.
        if isinstance(value, str):
            return value.lower()
        return value

Can you show your GQLAUTH_SETTINGS? including the implementations of email_field etc and a full stacktrace

Dude where do you get email_field from ?

[ash-lyrid]

Using the following. from gqlauth.settings_type import GqlAuthSettings, password_field, email_field

[nrbnlulu]

I see, thats weird. could you create a reproducible example?
