Solved.

Hi Kelvin,

OVS_CALLBACK_OBJECT is an importing parameter which is generated automatically. I think you have missed to enter the OVS event in your ON_OVS method. Create ON_OVS method as event handler and then press F4 in the event column and select the OVS event. OVS_CALLBACK_OBJECT will be created automatically.

I hope it helps.

ON_OVS method how did you created this method?

You have to assign the OVS Event to the Event handler method. Say F4 on the fourth column in the Methods Tab
