Error adding ONVIF camera (XMLParseError: No namespace defined for 'ter')

It seems this module is used in https://github.com/hunterjm/python-onvif-zeep-async and finally in Home Assistant Core https://github.com/home-assistant/core

I have reported this issue https://github.com/home-assistant/core/issues/45513 few months ago without any progress.

Probably you can help to investigate and fix the problem.

The component ONVIF inside Home Assistant Core contains the following requirements: "onvif-zeep-async==1.0.0", "WSDiscovery==2.0.0", "zeep[async]==4.0.0"

I got the error zeep.exceptions.XMLParseError: No namespace defined for 'ter' ('ter:InvalidArgVal') trying to add the camera Wanscam K21 or Wanscam K54 in Home Assistant. The full traceback is

The exception info is useless. I have recorded the full communication with the camera on PC using Wireshark. Here is the problem request:
