HTTP Error: 403 Client Error: Forbidden for url: https://auth.tesla.com/oauth2/v3/authorize

[eliaspfeffer]

Im getting this terminal error after writing the code for Step 2:

Step 1 - Login page obtained successfully.
Login data saved to file.
HTTP Error: 403 Client Error: Forbidden for url: https://auth.tesla.com/oauth2/v3/authorize
Please check your credentials and other parameters.

I can't figure out whats wrong. I've written the following code, following the documentation

What am I doing wrong? Have been troubleshooting since 2 days Python Version 23.1.2 (on windows if important)
