Running it on Magento Cloud I'm receiving this error below, could you help me with it?

I have the magepack root file in the server with the Composer module installed and enabled.
My .magento.app.yaml is like this below.

hooks:
    # We run build hooks before your application has been packaged.
    build: |
        set -e
        ./theme_compiler_install.sh
        ./theme_compiler.sh
        php ./vendor/bin/ece-tools build:generate

Using Magento 2.4.1, PHP 7.4

Installed Magepack and also Magepack Magento Module 1.1.4

Module is enabled, but the option to turn Magepack on is missing from Admin panel in Developer mode
Even trying to turn it on via CLI gives this error:

The "dev/js/enable_magepack_js_bundling" path doesn't exist. Verify and try again.

why do we use prefetch instead of preload?

I understand prefetch will only load JS when the CPU is idle while preload will transfer file from network first. So prefetch is not optimized to pagespeed, a better option might be "preload"+"async" ?

Currently the module is using "prefetch" link tags to hint the browser how scripts should be loaded:
https://github.com/magesuite/magepack-magento/blob/1.x/view/frontend/templates/bundles-loader.phtml#L10-L14

However prefetch is used to hint the browser about resources that will most likely be used on the next navigation, considering the scripts are loaded on the page they're supposed to be used this doesn't make a lot of sense.

Shouldn't this be using "preload" instead? The scripts are definitely needed on the page they're loaded on so it would help to get the browser to load them as soon as possible.

Hello

Is it normal that Magento is still charging the min.js file for the current the page ?

If yes why ?
If no, is it possible to remove it ? On other tests this min file take a long time to be executed.

Thanks.

Hi, I tried to install this module via composer, but couldn't.
Could you register this module into packagist?

MagePack is loading its JS before the CSS. And this makes the page look ugly while loading the page.

The order in which JS & CSS are loaded are (for example for Homepage):

<link rel="prefetch" as="script" href="./magepack/bundle-common.min.js"/>  
<link rel="prefetch" as="script" href="./magepack/bundle-cms.min.js"/> 
<...css files...>

Question: How to make the JS load after the CSS? or Defer to the footer?
Note that Move JS code to the bottom of the page = Yes

Hello Team,

I have started looking at this pack for bundling and performance improvement so I have installed the magepack and after executing the "magepack bundle" I am getting the below error

magepack bundle
ℹ Using bundling config from "/var/www/html/localproject/magepack.config.js".
ℹ Creating bundles for "pub/static/frontend/Magento/luma/en_US".
ERROR bundlingConfig.forEach is not a function
at /home/user/.nvm/versions/node/v14.4.0/lib/node_modules/magepack/lib/bundle.js:34:24

Magepack version = 2.8.0
Node version = v14.4.0
Magento 2.4.1 open source

Could you please help me out?? I really need this.

Polyfill.io has recently been bought by a Chinese adware company (source https://sansec.io/research/polyfill-supply-chain-attack)
So for security reasons all packages requiring polyfill need to be updated, in this package that would be puppeteer.

Is there a timeline for PHP 7.4 and Magento 2.4 support?
