What did you mean under "Nova API log"? I'm did attach journalctl output. Now I can't attach nothins. I did remove virtualbox image and install new stock image Ubuntu 16.04. In new image I before install devstack checkout to stable/ocata branch. Ocata worked is good, sending me 200-success response from my "GET /compute/v2.1/servers" request.
P.S. Sorry my English wery bad.)

I mean the full call back of the error

exceptions.TypeError is too hard to know where's the error ,if you have a callback stack, then it might know where's the problem and in addition, some configuration such as nova.conf will be helpful as well, from your description, I would think it's likely caused by some misconfiguration..
