Свойство BadRequestError: BLOB, ENITY_PROTO или TEXT concise_topics должно быть в поле raw_property

Вот код моей модели.

from google.appengine.ext import ndb from modules.admin.models.Author import Author from modules.hod.models.Concept import Concept class Post(ndb.Model): author_key = ndb.KeyProperty(kind=Author) content = ndb.StringProperty(indexed=False) created = ndb.DateTimeProperty(auto_now_add=True) title = ndb.StringProperty(indexed=True) topics = ndb.StructuredProperty(Concept, repeated=True) def get_important_topics(self): return filter(lambda x: x.occurrences > 1, self.topics) concise_topics = ndb.ComputedProperty(get_important_topics, repeated=True) 

Вот маршрут, который создает модель.

 @admin_home_routes.route('/SavePost', methods=['POST']) @authenticate_admin def save_new_post(): post_data = request.form['newpost'] new_post = Post(parent=posts_key()) author = get_author_by_email(users.get_current_user().email()) if len(author) > 0: new_post.author_key = author[0].key else: author = Author(parent=author_key()) author.email = users.get_current_user().email() author.name = users.get_current_user().email() author.identity = users.get_current_user().user_id() key = author.put() new_post.author_key = key new_post.content = post_data concepts = get_topics(post_data) _concepts = [] if len(concepts) > 0: for concept in concepts['concepts']: temp_concept = Concept(name=concept['concept'], occurrences=concept['occurrences']) _concepts.append(temp_concept) new_post.topics = _concepts new_post.put() return redirect('/Admin/Posts') 

Ошибка, которую я получаю
