Beta/Demo not supported?

[cyber-speed]

While testing couple of Demo/Beta i noticed they are not supported and i get this error:

Traceback (most recent call last):
  File "...\show_ps5_pkg_metadata.py", line 192, in <module>
    param_json = get_param_json(args.url, args.output)
  File "...\show_ps5_pkg_metadata.py", line 78, in get_param_json
    return json.loads(json_data)
  File "...\AppData\Local\Programs\Python\Python38\lib\json\__init__.py", line 357, in loads
    return _default_decoder.decode(s)
  File "...\AppData\Local\Programs\Python\Python38\lib\json\decoder.py", line 337, in decode
    obj, end = self.raw_decode(s, idx=_w(s, 0).end())
  File "...\AppData\Local\Programs\Python\Python38\lib\json\decoder.py", line 355, in raw_decode
    raise JSONDecodeError("Expecting value", s, err.value) from None
json.decoder.JSONDecodeError: Expecting value: line 1 column 1 (char 0)

I didn't post the link of said Beta/Demo that causes the error as i am not sure if its allowed?
