TypeError: 'NoneType' object is not subscriptable

Hi all,

We get this error after install and setup:

Unexpected error fetching carelink data
Traceback (most recent call last):
File "/usr/src/homeassistant/homeassistant/helpers/update_coordinator.py", line 379, in _async_refresh
self.data = await self._async_update_data()
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
File "/config/custom_components/carelink/init.py", line 161, in _async_update_data

File "/config/custom_components/carelink/api.py", line 390, in get_recent_data
if self.__session_user["role"]
~~~~~~~~~~~~~~~~~~~^^^^^^^^
TypeError: 'NoneType' object is not subscriptable

What should be the problem?

Thanks,
Gábor

It seems there is no user session when checking for the role of the account. I made a small change to log an error when this happens instead of crashing. Maybe this helps.

Thanks. The error is gone away, but got new:
/config/custom_components/carelink/init.py:88: SyntaxWarning: invalid escape sequence '.' date_iso = re.sub(".\d{3}Z$", "+00:00", date)

This is just a syntax warning and nothing that should break the app. I will fix it still, because not exactly what you would like.

I'd like to connect my device and get the data 😄
It's connecting, but is see unknow state on every sensor. Now only this relevant warning shows up in the log:

Detected blocking call to open with args ('custom_components/carelink/logindata.json', 'r') inside the event loop by custom integration 'carelink' at custom_components/carelink/api.py, line 406: token_data = json.loads(open(filename, "r").read()) (offender: /config/custom_components/carelink/api.py, line 406: token_data = json.loads(open(filename, "r").read()))
