npm run build -> Why does the "dist" folder have a "localhost:3000" code?

package.json

"dev": "nodemon",
"build": "next build && tsc --project tsconfig.server.json",
"start": "cross-env NODE_ENV=production node dist/server/index.js",

.evn.production

PORT=8080
NEXT_PUBLIC_BASE_URL="http://localhost:8080"
NEXTAUTH_URL_INTERNAL=${NEXT_PUBLIC_BASE_URL}
NEXTAUTH_URL=${NEXT_PUBLIC_BASE_URL}
VERCEL_URL=${NEXT_PUBLIC_BASE_URL}

When the commands "npm run dev" and "npm run start" are executed together, it operates normally.

help me plz...
