I made a deploy of this page, it is a backend app created with node.js express for a mysql database. And I get server error --> https://serverwebpage-production.up.railway.app/ --> this is what I got in deploy logs --> npm WARN config production Use --omit=dev instead.

server_web_page@1.0.1 start

node ./server.js
