    Vite by default uses an html page as an entry point. So you either need to create one or if you don’t have an html page you can use it in "Library Mode".

    https://vitejs.dev/guide/build.html#library-mode

    From the docs:

    // vite.config.js
const path = require('path')
const { defineConfig } = require('vite')

module.exports = defineConfig({
  build: {
    lib: {
      entry: path.resolve(__dirname, 'lib/main.js'),
      name: 'MyLib',
      fileName: (format) => `my-lib.${format}.js`
    },
    rollupOptions: {
      // make sure to externalize deps that shouldn't be bundled
      // into your library
      external: ['vue'],
      output: {
        // Provide global variables to use in the UMD build
        // for externalized deps
        globals: {
          vue: 'Vue'
        }
      }
    }
  }
})

    If you’re using ES Modules (i.e., import sytax):

    Look in your package.json to confirm type field is set to module:

    // vite.config.js
import * as path from 'path';
import { defineConfig } from "vite";

const config = defineConfig({
  build: {
    lib: {
      entry: path.resolve(__dirname, 'lib/main.js'),
      name: 'MyLib',
      fileName: (format) => `my-lib.${format}.js`
    },
    rollupOptions: {
      // make sure to externalize deps that shouldn't be bundled
      // into your library
      external: ['vue'],
      output: {
        // Provide global variables to use in the UMD build
        // for externalized deps
        globals: {
          vue: 'Vue'
        }
      }
    }
  }
})

export default config;

    Had same issue because of .dockerignore. Make sure your index.html not ignored.
    In case if you ignoring everything (**) you can add !index.html to the next line and try.
