What's broken?

Response after completing the oauth2 redirection flow to get google calendar API access token for gcal integration.

Without refresh token in gcal_auth.json, gcal module breaks after sometime. We need to periodically fetch and store the new access token using refresh token.

Workaround

I am presently using quickstart.py script to get refresh token and access token, and store it in gcal_auth.json.

This is interesting. I haven't had this problem and I've been using the gCal module since the beginning. I wonder if the expires_at is a new value, and my token has no expiry attached to it?

This is still an issue. What's more interesting, the token.json as generated by quickstart.py does not work with wtfutil. I have the quickstart.py in ~/.config/wtf/gcal/, in my config file in gcal section I have

secretFile: "~/.config/wtf/gcal/token.json"

and after removing token.json, running quickstart.py, going through the OAuth dance, and running wtfutil I get

oauth2/google: no credentials found

Which is even more annoying when the token eventually expires and I have to figure out again how to make it work.
