Im trying to deploy my sveltekit website, i tried everything but i keep getting this in the logs, my website works perfectly fine, but this shows up, what is the reason and should it be like this?
npm error path /app
npm error command failed
npm error signal SIGTERM
npm error command sh -c node build/index.js
npm error A complete log of this run can be found in: /root/.npm/_logs/2025-12-03T23_11_49_776Z-debug-0.log

update your package.json start script to this : "start": "node build"
and replace your entire config with this:
import adapter from '@sveltejs/adapter-node';
import { vitePreprocess } from '@sveltejs/vite-plugin-svelte';
/** @type {import('@sveltejs/kit').Config} */
const config = {
preprocess: vitePreprocess(),
kit: {
adapter: adapter({
out: 'build',
precompress: false,
envPrefix: ''
})
}
};
export default config;
then go to your Railway project settings and add: NODE_ENV = production and ORIGIN = https://your-app-name.up.railway.app (use your actual railway url)
also create a railway.json in your project :
{
"$schema": "https://railway.app/railway.schema.json",
"build": {
"builder": "NIXPACKS",
"buildCommand": "npm install && npm run build"
},
"deploy": {
"startCommand": "node build",
"restartPolicyType": "ON_FAILURE",
"restartPolicyMaxRetries": 10
}
}
push and deploy your deployment should succeed after these changes

your start script is using the wrong command. SvelteKit with adapter-node doesn't run with node build/index.js ,that's causing the SIGTERM and command failed errors
