Unattended Provisioning Could not find method: createSystemRecord

Hello All
I am new to SUMA. I am testing Autoinstallation which worked well so far but I want to do it without any user intervention. Therefore I am looking at Unattended Provisioning option. Following the documentation for SUMA 5 the following command has given an error:

*uyuni-server:/ # spacecmd api – --args '[“client1”, “SLEMicro55”, “”, “”, *

  • [ {“name”: “eth0”, “mac”: “00:50:56:ad:b1:0f”} ]]’ system.createSystemRecord*
    INFO: Connected to http://localhost/rpc/api as admin
    ERROR: <Fault -1: ‘redstone.xmlrpc.XmlRpcFault: Could not find method: createSystemRecord in class: com.redhat.rhn.frontend.xmlrpc.system.SystemHandler with params: [com.redhat.rhn.domain.user.legacy.UserImpl, java.lang.String, java.lang.String, java.lang.String, java.lang.String, java.lang.String, java.lang.String]’>
    uyuni-server:/ #

Does anybody have experience? Any help appreciated.

Thanks
