Did you try to use not JSON but usual GET/SET? Do you have the same issue?
AFAIK - ndb_redis is a wrapper oven hiredis wrapper and doesn't implement
serialisation protocol for redis, so, whatever you send delivered to redis
being only wrapped via hirer's client library.
Btw if uou use lua < 5.2 you may try redis-lua library. It is easier to use
with lua.
