vnf-create fails with TypeError: <type 'NoneType'> can't be decoded

[Sridhar Ramaswamy]

Hi,

I am new to tacker and trying out it. I successfully install it on devstack using the provided sample local.conf, and I can create a VNFD using "tacker vnfd-create --name sample-vnfd --vnfd-file sample-vnfd.yaml"

But when I tried to deploy the sample vnf using the UI or" tacker vnf-create --name sample --vnfd-id ba48**********", I always got ERROR status. Below are the logs of the traceback. Can someone help me identify what's the problem. Thanks a lot!

It could be related to the requirement problem. Can u repeat the error in new trunk tacker?

Reducing severity as the issue is related to wrong error status.
