Я работаю с некоторой документацией по API облачного хранилища данных Google
from google.cloud import datastore
datastore_client = datastore.Client(project="PROJECTNAME")
query = datastore_client.query(kind='Video')
r = query.fetch()
for v in r:
key = datastore_client.key('VideosToCollections')
entity = datastore.Entity(key=key)
entity['collection_key'] = key
datastore_client.put(entity)
quit()
Однако я получаю эту ошибку при обновлении записи
Traceback (most recent call last):

Я хочу, чтобы приведенный выше код создавал один объект VideosToCollections в качестве ступеньки, но расширится до создания одного для каждого видео. Любые мысли о том, что вызывает вышеуказанную ошибку, будут оценены.
