do you have public repo for the railpack configs? I can run bun flawlessly on railway with the auto detected railpack, but I'm having issues with building a docker image for my own servers. curious what you guys are doing differently

I see your CMD, I recommend you set it to RUN ["bun", "run", "dist/YOUR_MAIN_FILE.js"] as using package.json scripts can be finicky
