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.
