Context Issue

[ayushkhanduri]

I generated my build with the context name = books and base

<base href="/books/"/>

below is my configuration

{
    routes: ['/location/bangalore'],
    timeout: 5000,
    dimensions: {
      width: 375,
      height: 812,
    },
    https: false,
    hostname: 'http://localhost/books',
    useragent: 'Prep',
    minify: true,
    concurrency: 4,
    additionalSitemapUrls: [],
  }

Then i run this command

// books contain the index.html 
prep ./books/ ./build  

It retries 10 times and i get the error

ChildProcessError: Command failed: cp -rf "/Users/b0219479/Documents/Acquisition/react-growth-safo-ui/.prep-tmp"/* "/Users/b0219479/Documents/Acquisition/react-growth-safo-ui/build"/
