I'm trying to set up continuous deployment for a project. Right now, I manually pull from main on Github then do railway up. I've set up a deploy.yml to do that automactically after every commit to main. However, it keeps saying my token is invalid. I've tried workspace and account tokens, copied from railway and put directly into Github as secrets. But it still says they're not valid. They don't work for commands like 'RAILWAY_TOKEN=your-token npx railway whoami' either. Any ideas why my tokens don't work?
