BadRequest: object of type 'NoneType' has no len() (HTTP 400)

RHEL 6.5.

I attempted to create an instance via HEAT. The creation of the instance failed (which I expected, no problem there). However, when the instance was being rolled back, the final status came back with (from the heat.log file) failed status, and:

BadRequest: object of type 'NoneType' has no len() (HTTP 400)

Any suggestions?

Check the logs from nova, too, see if there is something weird there.

It's been a while since you asked, sorry we are trying to keep up.

Did you get to the bottom of it? This looks like a bug, so feel free to raise it here: and add as much info (logs, templates, parameters) as you can.
