SSL Certificate Verify Failed: certificate has expired (_ssl.c:1076)')))

I updated the alpaca-trade-api python package from version 1.1.1 to version 1.5.1 and I have been getting an error trying to use the API since.

The error is as follows:

The code I am using that is giving me the error is the get_account() method.

api = tradeapi.REST(api_key, api_secret, base_url, api_version='v2')
account = api.get_account()

The expected behavior is to be able to connect without any issues to the Alpaca API. From what I have read online so far, this seems to be a certificate expiry issue on Alpaca end but have not found any concrete solutions so far and hence posting here.
