Hello Joe,
based on this
https://github.com/andymccurdy/redis-py/issues/1071#issuecomment-439199774
looks like Redis had a backward incompatible changes and keys in
dictionaries cannot be bool (values can).
I reviewed the web2py code and I can confirm no change on our side.
Random thoughts: It was a design mistake on my side to allow pickle to
store sessions. I should have used json. This would have restricted what
can go in a session but would have made the serialized session more
portable and the whole logic faster. In that case only str keys would have
been allowed. Web3py will use json for sessions or move away from sessions
completely.
