Your logs show that you app had a successful start (listening on port 8080) and that the container started, the crashing must be happening after those lines (which you trimmed)

Does it works locally?

It works perfectly, just that on every deploy I get a Deployment crashed email.

What is your start command?

Try this:

/bin/sh -c "cd build; exec node index.js" seems to have done the trick

start command was empty and hence npm run

You could add a custom Railpack setup or a Dockerfile setup to avoid these issues, but good to know you solved it.

Anything else before the thread is marked as solved?

Mark as solved! Thanks!!
