multiple errors on login / trying to connect to TI9555X9 coffee maker

[Morg42]

Hi,

I've been running the singlekey branch for a while now without problems, owning a dishwasher which I can access over hcpy.

System is Devuan daedalus, Python 3.11.2

Now I added a coffee maker (S500 connect, TI9555X9DE/21) and hc-login goes awry...

First error is "missing scheme" on the fourth preauth URL, which I fixed by prepending singlekey_host. (inserting 2 lines before line 123.

Next error is "failed to fetch <Response [307]>", which I fixed by adding code 307 to line 127.

Next error is a relative url for the first return_url, which I again fixed by prepending singlekey_host (again inserting 2 lines before line 136.

The next error is (subtract 4 from linenumbers for inserted code lines):

return_url='https://singlekey-id.com/auth/connect/authorize/callback?client_id=[...]&redirect_uri=https%3A%2F%2Fapi.home-connect.com%2Fsecurity%2Foauth%2Fredirect_target&response_type=code&scope=openid%20email%20profile%20offline_access%20homeconnect.general&prompt=login&style_id=bsh_
hc_01&state=%7B%22session_id%22%3A%22[...]%22%7D&suppressed_prompt=login'
Traceback (most recent call last):
  File "/home/sh/src/hcpy/./hc-login", line 142, in <module>
    headers["RequestVerificationToken"] = r.cookies["X-CSRF-FORM-TOKEN"]
                                          ~~~~~~~~~^^^^^^^^^^^^^^^^^^^^^

    raise KeyError(f"name={name!r}, domain={domain!r}, path={path!r}")
KeyError: "name='X-CSRF-FORM-TOKEN', domain=None, path=None"

I'm guessing it's missing the X-CSRF-FORM-TOKEN cookie from the response. Response cookies include .AspNetCore.Antiforgery. and __Host-F8Mmt.
Why? What can I do? What might I have done wrong?

Anyone able to help? As far as I could see, @CRTified has a similar machine already working...?

Hi, sorry for the lack of a response. I used to have this working with a coffee machine, but at that point the code was a mere PoC and not something that could be used productively. Since then, I didn't have time to dig into it any deeper, so I can't provide any recent insights.
