- Installing meetanshi/magento-2-defer-parsing-javascript (1.0.4): Downloading (connecting...) Downloading (failed)                                                                                                                                                                                                  [Composer\Downloader\TransportException]

Docker step with composer install

RUN set -eux; \
    mkdir /var/www/.composer; \
    chown www-data:www-data /var/www/.composer; \
    su -c "cd /var/www/html/ && composer global require hirak/prestissimo" -s /bin/sh www-data; \
    su -c "cd /var/www/html/ && composer install --no-dev --prefer-dist --no-interaction --optimize-autoloader" -s /bin/sh www-data; \
    rm -rf /var/www/.composer;

It's happening because you might not have the right setup, try to reinstall it using these commands below.

composer remove meetanshi/magento-2-defer-parsing-javascript
composer require meetanshi/magento-2-defer-parsing-javascript

Then you can run the Magento commands to recognize and compile your Magento.
