Error processing SAML response: 'Config' object has no attribute 'correctly_signed_response'

Hello all, please, need help with the config for saml2, I'm receiving this error, and have no idea how to add this attribute.

Error processing SAML response: 'Config' object has no attribute 'correctly_signed_response'

My saml config

def parse_authn_response(self, saml_response):
    # Load the IdP configuration and parse the SAML response
    saml_settings = {
        'metadata': {
            'remote': [{
                'url': OKTA_URL_METADATA,
                'cert': MY_CERT,
            }],
        },
        'service': {
            'sp': {
                'endpoints': {
                    'assertion_consumer_service': [(self.get_acs_url(), BINDING_HTTP_POST)],
                },
                'allow_unsolicited': True,
                'name_id_format': 'urn:oasis:names:tc:SAML:1.1:nameid-format:emailAddress',
            },
        },
    }

    config = Saml2Config()
    config.load(saml_settings)

    # Parse the response
    authn_response = AuthnResponse(config, saml_response, entity_id=sp.get_entity_id(), binding=BINDING_HTTP_POST)

Does anyone know what and how I can fix it ??

thanks
