AttributeError: 'list' object has no attribute 'items' in GlobalCache

[iseebi]

Hello,

I upgraded google-cloud-ndb to 1.10.2 from 1.8.0, and had a AttributeError in GlobalCache.
I'm using google-cloud-ndb with GAE/Python 3.7 or my local machine's Python 3.7 and Redis cache.
When I call get() method, I immediately got this error.

Can you tell what happened from the backtrace?

class PersonalData(ndb.Model):
    user_name = ndb.StringProperty(default="Guest", name="username")

It may caused from my patch for redis-py.
I close issue for now. Sorry.
