Fingerprint command fails while fetching charging session

Open mislav opened this issue 2 years ago • 11 comments

Describe the issue

Running bimmerconnected fingerprint <email> <password> rest_of_world fails when fetching charging sessions:

httpx.HTTPStatusError: Client error '404 Resource Not Found' for url 'https://cocoapi.bmwgroup.com/eadrax-chs/v1/charging-sessions?vin=<VIN>&maxResults=40&include_date_picker=true'

Expected behavior

The bimmmerconnected fingerprint command succeeds since these same credentials work with a MyBMW app.

Which Home Assistant version are you using?

n/a

What was the last working version of Home Assistant Core?

n/a

What is your region?

Rest of world

MyBMW website

[X] I can still successfully login to the BMW MyBMW website and the car status is available there.
[X] I have MyBMW enabled for my vehicle.

Number of cars

[ ] I have 2 or more cars linked to the MyBMW account.
[ ] I have a Mini vehicle linked to my account.

Output of bimmer_connected fingerprint

No response

Anything in the logs that might be useful for us?

Additional information

I have also tried the code in https://github.com/bimmerconnected/bimmer_connected/pull/458, but that fails with a different error:

DEBUG:httpx._client:HTTP Request: GET https://cocoapi.bmwgroup.com/eadrax-crccs/v1/vehicles/<VIN>?fields=charging-profile&has_charging_settings_capabilities=true "HTTP/1.1 500 Internal Server Error"

Thanks for the report! Can't test it myself, don't have an EV.

As you already used the code from #458, you try adding the following header: "24-hour-format": "true"?

Jun 20 '22 12:06 rikroe

@rikroe I've added the header but it doesn't seem to have any effect on the HTTP 500 error.

:/ Then I'm very much at a loss why it doesn't work. Just to double check: you are able to set charging profiles in the MyBMW app, right?

Jun 20 '22 18:06 rikroe

@rikroe I'm not sure what "charging profiles" in the app are. I'm using the app in Dutch language. The only charging settings that the app offers me is to change from "direct" (i.e. uninterrupted) mode of charging to only allowing charging between certain start time and end time.

However, if this is a feature that is not available to my car or region, I would have expected that the server would respond with something other than a HTTP 500. I reported this because I thought maybe the library sends some wrong parameters and triggers the 500 somehow. Maybe the library could treat server errors as non-fatal and just print them as warnings to stderr, but the figerprinting could allow to continue?

I've tried using the Home Assistant integration that uses this library, but it didn't allow me to log in (it would say that an error occurred). That's why I went to use the library directly to see if I can help report a bug better. I am able to run the status command but not the fingerprint command. I do not actually depend on the result of the fingerprint command for anything. Not sure which command is used for Home Assistant integration during login.

Thank you for maintaining this library!

I this case, you can ignore these charging endpoints for now. They are not used by the library at all and just part of the fingerprint to gather some more data.

Maybe your error has something to do with https://github.com/home-assistant/core/issues/73370 or https://github.com/home-assistant/core/issues/73713?

Jun 21 '22 07:06 rikroe

@rikroe I'll dig deeper for the cause of the HA failure. Thanks for the pointers!

You may close this issue at your convenience. 🙇

Jun 21 '22 11:06 mislav

While we don't need it right now, I would like to understand why some EVs are able to provide the eadrax-crccs/v1/vehicles/<VIN>?fields=charging-profile&has_charging_settings_capabilities=true endpoint and some don't.

Could you please provide the vehicles and state files from your fingerprint? Maybe there is a flag somewhere...

Jun 23 '22 08:06 rikroe

@rikroe Sure, which files do you need, and should I share it in the open here?

BTW I was able to add this vehicle to HA in my latest attempt. I think I might have been hitting rate limits (another known issue) when I first attempted to add it to HA.

Jun 23 '22 10:06 mislav

Please provide all files, they should be sanitised for personal information. Nevertheless please double check and edit out all data you're not happy to share.

The rate limiting can occur again and will be fixed soon by #462, when we don't use the old API endpoints anymore.

Jun 23 '22 11:06 rikroe

@rikroe Ok, here is the information: https://gist.github.com/8113c64c38f9998a75c878318725cac1
