open the file webpack.config.js

you have to add the line const bootstrapTheme = require('./themes/BootstrapTheme/webpack.config'); and update the export so as to have module.exports = [shopConfig, adminConfig, bootstrapTheme];

Here is the full code of the webpack after modification:

const path = require('path');
const Encore = require('@symfony/webpack-encore');

const bootstrapTheme = require('./themes/BootstrapTheme/webpack.config');

const syliusBundles = path.resolve(__dirname, 'vendor/sylius/sylius/src/Sylius/Bundle/');
const uiBundleScripts = path.resolve(syliusBundles, 'UiBundle/Resources/private/js/');
const uiBundleResources = path.resolve(syliusBundles, 'UiBundle/Resources/private/');

// Shop config
  .addEntry('shop-entry', './assets/shop/entry.js')

const shopConfig = Encore.getWebpackConfig();

shopConfig.resolve.alias['sylius/ui'] = uiBundleScripts;
shopConfig.resolve.alias['sylius/ui-resources'] = uiBundleResources;
shopConfig.resolve.alias['sylius/bundle'] = syliusBundles; = 'shop';


// Admin config
  .addEntry('admin-entry', './assets/admin/entry.js')

const adminConfig = Encore.getWebpackConfig();

adminConfig.resolve.alias['sylius/ui'] = uiBundleScripts;
adminConfig.resolve.alias['sylius/ui-resources'] = uiBundleResources;
adminConfig.resolve.alias['sylius/bundle'] = syliusBundles;
adminConfig.externals = Object.assign({}, adminConfig.externals, { window: 'window', document: 'document' }); = 'admin';

module.exports = [shopConfig, adminConfig, bootstrapTheme];

open the file config/packages/assets.yaml

        #json_manifest_path: '%kernel.project_dir%/public/build/manifest.json'
                json_manifest_path: '%kernel.project_dir%/public/bootstrap-theme/manifest.json'  

open config/packages/webpack_encore.yaml

    # The path where Encore is building the assets - i.e. Encore.setOutputPath()
    #output_path: '%kernel.project_dir%/public/build'
    # If multiple builds are defined (as shown below), you can disable the default build:
    output_path: false

    # If using Encore.enableIntegrityHashes() and need the crossorigin attribute (default: false, or use 'anonymous' or 'use-credentials')
    # crossorigin: 'anonymous'

    # Preload all rendered script and link tags automatically via the HTTP/2 Link header
    # preload: true

    # Throw an exception if the entrypoints.json file is missing or an entry is missing from the data
    # strict_mode: false

    # If you have multiple builds:
    # builds:
        # pass "frontend" as the 3rg arg to the Twig functions
        # {{ encore_entry_script_tags('entry1', null, 'frontend') }}

        # frontend: '%kernel.project_dir%/public/frontend/build'

    # Cache the entrypoints.json (rebuild Symfony's cache when entrypoints.json changes)
    # Put in config/packages/prod/webpack_encore.yaml
    # cache: true

        bootstrapTheme: '%kernel.project_dir%/public/bootstrap-theme'

in package.json modify the following versions:

"node-sass": "4.14.1",
"sass-loader": "^9.0.1",

Then run the commands
