'Not supported on the object error' while deploying OVF

Hello, I am trying to make a python script to deploy OVF on vSphere. https://gist.github.com/goindwalia/48a5f9ab6a2f4eedfdba The error I am getting is leading me no where:

(vmodl.fault.NotSupported) {
   dynamicType = <unset>,
   dynamicProperty = (vmodl.DynamicProperty) [],
   msg = 'The operation is not supported on the object.',
   faultCause = <unset>,
   faultMessage = (vmodl.LocalizableMessage) []
}

The lease is getting failed after initialising. I am having strong feeling that there is something wrong while creating ImportVApp or CreateImportSpec. I have tried 2-3 different minimal OVFs so far. Kindly help me rectifying this error.

@derchrisuk well that was simple.

Changing one line makes it work for both ESXi host and directly to vCenter:

    lease = objs["resource pool"].ImportVApp(import_spec.importSpec, objs["datacenter"].vmFolder);
