Error in Enable link mode

[workinregress]

Hi, I'm trying to configure Emulated Hue. I run HA in docker on a debian12 machine.
When I click on Enable link mode i get this error:
404 Not Found

The logs reports:
023-11-06 12:52:33,085 ERROR aiohttp.server -- Error handling request
Traceback (most recent call last):
File "/usr/local/lib/python3.10/site-packages/aiohttp/web_protocol.py", line 332, in data_received
messages, upgraded, tail = self._request_parser.feed_data(data)
File "aiohttp/_http_parser.pyx", line 551, in aiohttp._http_parser.HttpParser.feed_data
aiohttp.http_exceptions.BadStatusLine: 400, message="Bad status line 'Invalid method encountered'"

more specifically i looked for the folder /usr/local/lib/python3.10/site-packages/aiohttp/web_protocol.py inside HA folders and it doesn't exist (/usr/local/lib/ is empty), outside home assistant, I run python3.11 so i python3.11 folder and not python3.10

how can I solve this issue?

thanks
