In stein, with use of token caching, token deserialization is returning list object instead of keystone.models.token_model.TokenModel object causing it to fail in token validation.

I'm unable to recreate this. I added some additional logging output to help diagnose the problem [0]. I setup caching [1] and I repeatedly validated a token. The logs include additional logging that shows the token being fetched from the cache [2].
Here is a list of the packages I have installed locally, from devstack [3].
Let me know if there is anything else I can do to try and recreate this.
