Python ONVIF GotoPreset failed to set global movment Speed

[Kowa92]

I'm trying to set the point called "Preset001" with a well-defined Speed but I can't as I get the following error on console:

My camera's hostname: MYCAM
    gotoPreset:
    {
        'ProfileToken': 'MainStreamProfileToken',
        'PresetToken': 'Preset001',
        'Speed': 0.1
    }

This is the Script that executes the Preset command (without setting the speed, this one command works perfectly):

    #!/usr/bin/python3

    from functions import *

    from onvif import ONVIFCamera

    mycam = ONVIFCamera('xxx.xxx.xxx.xxx', 8080, 'admin', 'password', '/home/pi/.local/lib/python3.4/site-packages/wsdl/')

    # Get Hostname
    resp = mycam.devicemgmt.GetHostname()
    print("My camera's hostname: " + str(resp.Name))

    # Create media service object
    media = mycam.create_media_service()

    # Get target profile
    media_profile = media.GetProfiles()[0]
    #print(media_profile)

    # Create ptz service object
    ptz = mycam.create_ptz_service()

    request = ptz.create_type('GotoPreset')

    request.ProfileToken = media_profile.token

    request.PresetToken = "Preset001"

    request.Speed = 0.1

    print("gotoPreset:")
    print(request)

    print(ptz.GotoPreset(request))

I am using this ONVIF Python LIbrary on RaspberryPi 4.

• Would anyone know how to give me some advice?
• Where am I wrong?

Thanks to anyone!

Speed is a dict like: request.Speed = { "PanTilt": {"x": 0.0025, "y": 0.0025}, "Zoom": {"x": 0.0025} }

Ok thanks it works!

Although the PTZ does not seem to vary its speed of movement. I think that this last feature is not supported.. Could it be ??
