Canada NCI login fails "INVALID PARAMS" from HTTP Response Body

[fermulator]

Good day,

Initially tried this via https://www.home-assistant.io/integrations/nissan_leaf/, however it didn't work with:

Feb 08 16:45:44 hass hass[2545]: 2020-02-08 16:45:44 ERROR (SyncWorker_9) [pycarwings2.pycarwings2] carwings error INVALID PARAMS: -2010
Feb 08 16:45:44 hass hass[2545]: 2020-02-08 16:45:44 ERROR (SyncWorker_9) [homeassistant.components.nissan_leaf] An unknown error occurred while connecting to Nissan: <(snipped/lost)

Reproduced it with my account hitting Canada NCI portal using latest pycarwings2:

As per the README.md, did the basic install, and copied down some examples w/ my_config.ini.

$ python3 --version
Python 3.6.8

$ pip3 list | egrep "pycar|chardet|urllib3"
chardet                  3.0.4                 
pycarwings2              2.9                   
urllib3                  1.25.8                

~/.local/lib/python3.6/site-packages/pycarwings2/examples$ ll

drwxrwxr-x 2 fermulator fermulator 4096 Feb  8 20:05 ./
drwxrwxr-x 4 fermulator fermulator 4096 Feb  8 19:57 ../

-rw-rw-r-- 1 fermulator fermulator  148 Feb  8 19:59 my_config.ini

Had to tweak get-leaf-info.py to hit my python3 directly (not env python), otherwise it is left unmodified.

After that, it ran, and repro'd the problem:

Open to working through/debugging (just filing the issue report for now). If anyone has guidance happy for it to get a jump start.

It may be worth noting (since I'm not sure if different regions have different account rules):

• my username is an e-mail address ([email protected])
• my password has special chars in it (alphanumeric + @, -)
