X-Press Publishing Project - npm run build not working

Hello, I’m trying to deploy the project on Netlify but sadly typing “npm run build” on the terminal it doesn’t work as expected.

PS C:\Users\hp\Desktop\Web Dev\Codecademy\API\capstone-project-1-x-press-publishing> npm run build
npm ERR! Missing script: “build”
