Unknown Property service_interface_type_list

[Hafiz]

Hi,
I'm trying to create a service instance and a service template from a HOT.
Below is a part of the HOT

service_template_01:
    type: OS::Contrail::ServiceTemplate
    properties:
      name: { get_param: svc_tmp_name }
      service_mode: "In-network"
      service_type: "Firewall"
      image_name: "vsrx"
      flavor: "m1.medium"
      service_interface_type_list: { "Fn::Split" : [ ",", Ref: service_interface_type_list ] }
      shared_ip_list: { "Fn::Split" : [ ",", Ref: shared_ip_list ] }

  service_instance:
    type: OS::Contrail::ServiceInstance
    depends_on: [private_subnet_1, private_subnet_2]
    properties:
      name: { get_param: svc_ins_name }
      service_template: { get_resource: service_template_01 }
      availability_zone: "AZ"
      scale_out:
          max_instances: { get_param: max_instances }
      interface_list: [
          { virtual_network: "auto" },
          { virtual_network: {get_resource: private_net_1} },
          { virtual_network: {get_resource: private_net_2} },
      ]

When I try to create the stack I get the below error:
ERROR: Property error: : resources.service_template_01.properties: : Unknown Property service_interface_type_list

It doesn't recognize the property service_interface_type_list of OS::Contrail::ServiceTemplate
I made sure that the resources are defined in heat.conf
