I have attempted to setup & deploy cal.com on railway via the template, docker image, and source code, with no success.

I see that the template at https://github.com/railwayapp-templates/calendso is archived, I'm not sure how well this is supported now.

I had the most success with the template, however the best I could do was get it to stop posting warnings or errors, and it would just exit without a message.

I was told over on the github issues page that the template expects you to setup a connection to a Google account - I neither have nor want one of those.
