найти проблему JSON форматирования с обработчиком ошибок в приложении flask?

, поэтому я получаю эту странную ошибку, когда пытаюсь запустить свой юнит-тест ошибки Auth с POST, PATCH, DELETE. Нет проблем с запросами GET, у которых также есть @ require_auth.

По сути, идея состоит в том, что если токен-носитель Auth0 отсутствует, операция не может быть завершена.

вот ошибка: 

    [2020-03-20 10:08:45,782] ERROR in app: Exception on /donors/1 [DELETE]

    }, 401)
auth.AuthError: ({'code': 'authorization_header_missing', 'description': 'Authorization header missing'}, 401)

During handling of the above exception, another exception occurred:

}

вот мой код: 

   @app.route('/donors/<int:donor_id>', methods=['DELETE'])
    @requires_auth('delete:donors')
    def delete_donor(payload, donor_id):
        try:
            donor_to_delete = Donor.query.filter(Donor.id ==
                                                 donor_id).one_or_none()
            donor_to_delete.delete()

            return jsonify({
                'success': True,
                'delete': donor_id
                })

        except:
            abort(404)

Код Unittest: 

def test_delete_donors_true(self):
    res = self.client().delete('/donors/1', headers=inventory_manager_auth)
    data = json.loads(res.data)

    self.assertEqual(res.status_code, 200)
    self.assertEqual(data['success'], True)
    self.assertEqual(data['delete'], '1')

Обработчик ошибок приложения: 

@app.errorhandler(401)
def Unauthorized(error):
    return jsonify({
                    "success": False,
                    "error": 401,
                    "message": "Unauthorized"
                    }), 401
