Unable to update traffic flow when test is running.

[sngx13]

Hi, I'm having issues regenerating traffic flow when "FrameRate" is updated on the fly (while loop based on packet loss of the "Traffic Item Statistics" this is obviously possible via the GUI. Code snippet:

    traffic_config = traffic_item.ConfigElement.find()
    traffic_item.Generate()
    ixnetwork.Traffic.Apply()
    ixnetwork.Traffic.StartStatelessTrafficBlocking()
    traffic_item_statistics = session.StatViewAssistant(
        'Traffic Item Statistics'
    )
    #
    total_loss = float(traffic_item_statistics.Rows['Loss %'])
    while total_loss < 1:
        print(
            f'[+] Current total loss: {total_loss}%'
        )
        initial_rate += 50
        print(
            {
                'total_tx_frames': traffic_item_statistics.Rows['Tx Frames'],
                'total_tx_rate_mbps': traffic_item_statistics.Rows['Tx Rate (Mbps)'],
                'total_rx_frames': traffic_item_statistics.Rows['Rx Frames'],
                'total_rx_rate_mbps': traffic_item_statistics.Rows['Rx Rate (Mbps)'],
                'total_loss': traffic_item_statistics.Rows['Loss %']
            }
        )
        sleep(10)
        traffic_config.FrameRate.update(
            Type='bitsPerSecond',
            Rate=initial_rate
        )
        traffic_item.Generate() <--------------------------
        ixnetwork.info(
            ixnetwork.Traffic.TrafficItem.find()
        )
        if total_loss > 1 or initial_rate == 1000:
            print('[+] Loss exceeded 1%')
            # Stop the test
            ixnetwork.info('[+] Stopping the test...')
            ixnetwork.Traffic.StopStatelessTrafficBlocking()
            break
