Ports not exposed in NextJS app with nixpacks

I couldn't find information on the internet, I have basic nextjs14 app that needs ports exposed as .env variable set in Dokploy is "PORT=3002" and for some reason nixpacks don't detec't the port resulting in making Docker container that has not exposed ports, which means the app is not accessible by anyone. How do I fix that, because I can manually make "docker run [my created docker container here]" but that makes me doing everything from scratch and Dokploy isn't a solution then.

You don't need to expose the port to the main machine. Go to Domains and create a new random-generated domain, then add the port for your NextJS app.

Thanks, after fixing some issues in my side now I have situation where chat gpt is not so much helpful. Have you got any idea why trafeik makes me result of my website as “bad gateway” when accessing it trought browser but when I acccess it using http:3000 it works perfectly? Not sure even what logs to give you because there are no errors
