Solve the following python programming problem given the following code:
def test_process_message(self) : 
    msg_runner = fakes.get_message_runner ('api-cell') 
    dispatcher = rpc_driver.InterCellRPCDispatcher (msg_runner) 
    message = messaging._BroadcastMessage (msg_runner, self.ctxt, 'fake', { 
        
}, 'down', fanout = True) 
    call_info = { 
        
} 
    def _fake_message_from_json(json_message) : 
        call_info ['json_message'] = json_message 
        self.assertEqual (message.to_json (), json_message) 
        return message 
def _fake_process() : 
        call_info ['process_called'] = True 
self.stubs.Set (msg_runner, 'message_from_json', _fake_message_from_json) 
    self.stubs.Set (message, 'process', message) 
    dispatcher.process_message (self.ctxt, message.to_json ()) 
    self.assertEqual (message.to_json (), call_info ['json_message']) 
    self.assertTrue (call_info ['process_called']) 

    
    

    Fix the buggy line: self.stubs.Set (message, 'process', message)

#Here is Python program to fix the buggy line: self.

self.stubs.Set (message, 'process', def _fake_process()
