Calling call_refresh_token results in HTTP 400 Error: Bad Request

[asharma13524]

First, just wanted to say thanks for such an awesome library. Now, I am obtaining an HTTP Error 400: Bad Request when attempting to send an email. I thought that the issue was being caused by an unexpired token perhaps. I could not quite track down exactly why this error was happening. But I run this scraper ~ once a week and after about a couple of months, this error started popping up.

Both the error and the relevant code that is producing the error can be found below.

Traceback (most recent call last):

    raise HTTPError(req.full_url, code, msg, hdrs, fp)
urllib.error.HTTPError: HTTP Error 400: Bad Request

Here is the relevant code in my script using the pattern you describe in the docs.

yag = yagmail.SMTP("email", oauth2_file="/home/mattwilliams1760/oauth2_creds.json") 
                yag.send(
                    to=["email", "email"],
                    subject="subject",
                )

I have all credentials in the oauth2_creds.json file in the following format:

{"email_address": "email address", "google_client_id": "client id", "google_refresh_token": "google refresh token", "google_client_secret": "google client secret"}

Any help would be greatly appreciated in tracking down what is going on. Please let me know if anything else is needed to help understand what is going on, I am still a bit of a beginner. My entire repo can be found here: https://github.com/asharma13524/clinical-trials-scraper

Yea I am not sure, I think OAuth2 possibly might not work anymore. I'd recommend switching to application specific passwords - this is my current way.

Hope it's useful to you!
