Any suggestions?

I am getting the error below. Any suggestions?

In my experience, errors like this come and go. They seem to play with the API from time to time.

I think there is a new problem now though with Captcha being added as discussed here: timdorr/tesla-api#390

[jakkaj]

I managed to work around the captcha by grabbing a token in Postman using the built in authentication stuff, then popping it in a json file and removing direct user and pass. Works for MFA too as you're just logging in a browser as you would in the app - and the tokens refresh anyway, so should never have to do it again hypothetically.

Settings for Postman that worked:

Client secret:c7257eb71a564034f9419ee651c7d0e5f7aa6bfbd18bafb5c5c033b093bb2fa3

[jakkaj]

This is the rest.

The START_TOKEN variable is a json token from .env to get things started (the one manually generated in postman)

It looks like this:

{"resfresh_token": "", "access_token": "", "expires_in": 28800, "created_at": 1622326394.014721}

async def save_token(token):
    open("token_file.json", "w").write(token)

async def load_token():
    try:
        with open('token_file.json', "r") as f:
            return f.read()        
    except IOError:
        await save_token(START_TOKEN)
        return await load_token()    
    


async def getreserve():
    token = await load_token()
    client = TeslaApiClient(token=token, on_new_token=save_token)

Just create a new request and switch to the authorization tab and you should see it. BTW you don't need an account in Postman!

I deleted my previous response out of embarrassment but thank very much for holding my hand. I don't know why I couldn't fumble my way through the UI to find this!

[jakkaj]

I find it to be unintuitive... could be a better UI .

There is a problem I've come across now that the code does not refresh the tokens properly, gives an invalid_grant error with a grant type of refresh_token. Have not had time to really pull it apart yet. Will create a new issue.

[bchristian14]

the code does not refresh the tokens properly

well that's unfortunate. I think I maybe saw this when I first wrote my script, but probably just attributed to my lack of understanding/knowledge, and just pass the credentials each time (the script only has 1 user - me!)

[jakkaj]

The auth token works fine, just when it expires the refresh step fails.

[fracai]

Thanks @jakkaj, your token suggestion is working for me and but I'm also seeing the refresh step failing.
The error I get is:

...
  File ".../.venv/lib/python3.8/site-packages/tesla_api/__init__.py", line 61, in _get_token
    raise AuthenticationError(response_json)
tesla_api.exceptions.AuthenticationError: Authentication to the Tesla API failed: {'error': 'invalid_grant', 'error_description': 'The provided authorization grant is invalid, expired, revoked, does not match the redirection URI used in the authorization request, or was issued to another client.'}

The "issued to another client" makes me wonder if the OAUTH_CLIENT_ID is the problem. I note that tesla_api uses 81527cff…, but the Postman process uses ownerapi. I tried getting a token using the 81527cff… ID, but that resulted in an error in the authorization popup. I tried changing OAUTH_CLIENT_ID to ownerapi for just the _get_token method, but resulted in the same error response.

[fracai]

I was able to refresh the token!

I used ownerapi for the client id, https://auth.tesla.com/oauth2/v3/token for the URL, and added "scope": "openid email offline_access" to the refresh data. I'm not sure if scope is actually required here. I saw it used in a refresh on another project and haven't tried it without. I then also added created_at to the response_json to support the refresh check.

I can make a proper PR, but for now my changes are below:

Looks like some of my changes are covered by the v3 PRs that already exist.
#38
#39

[jcam]

This project seems to handle the captcha pretty well, might be useful to lift some of their work:
tdorssers/TeslaPy@22540ab

[jakkaj]

@fracai sweet!

[jakkaj]

@jcam Seems like a lot of extra work around to handle Capcha. This really looks like a lot of work when perhaps a one time interactive login is needed + decent token refreshing.
