I'm able to do Google auth completely normal on my localhost, but when I deploy to Vercel I get an error:
https://resume-manager-five.vercel.app/api/auth/signin/google 405 (Method Not Allowed)
What's really strange is at one point it was working, but at some point doesn't work. I've verified the environment variables, I've looked at the Google console, and everything seems fine. I've spent almost a full day on this trying to start from scratch etc, but have given up.
