Comment 3 for bug 1662704

Sorry for miss communication, here the flavor is for nova flavor.
As mentioned in below template section, I had created a flavor named "my_flavor".

  node_templates:
    VDU1:
      type: tosca.nodes.nfv.VDU.Tacker
      properties:
        image: cirros-0.3.4-x86_64-uec
        flavor: my_flavor
        availability_zone: nova
        mgmt_driver: noop
        config: |
          param0: key1
          param1: key2

Before ns-create, I deleted it from nova side.
.. nova flavor-delete my_flavor

But actually my point is not about flavor only.
In case any exception in VNF create, this error will be produced.
