I have a really strange problem. We load a JS file in before.body.end in a multistore setup, like this:


    <referenceContainer name="before.body.end">
        <block class="Magento\Framework\View\Element\Template" template="Magento_Theme::js/js.phtml" name="module_js"/>


<script type="text/javascript" defer="defer">
require(['jquery', 'fancybox', 'domReady!'],
    function($, fancybox, doc) {
        var fancyboxExample = {
            openModal: function() {
            closeModal: function() {

This works perfect, but for some store views, the path is wrong when checking the console:

*Error message in web browser console:
Failed to load resource: the server responded with a status of 404 ()*

The path to the JS file gets duplicated with js/jquery.fancybox.min for some stores: /static/version1620396352/frontend/Vendor/Theme/sv_SE/js/jquery.fancybox.min/js/jquery.fancybox.min.js

All store views are sharing the same parent theme, where this JS include is being made. We use versioning and version1620396352 is working as expected. If we remove js/jquery.fancybox.min/js from the path above in the browser, the script is loaded correctly.

Update #1

Content in \app\design\frontend\Vendor\Theme\requirejs-config.js

var config = {
paths: {
shim: {
    'fancybox': {
        deps: ['jquery'] //gives your parent dependencies name here

Update #2

Error in var/log/debug.log

[2021-05-18 12:17:19] main.ERROR: Unable to resolve the source file for 'frontend/Vendor/Theme/sv_SE/js/jquery.fancybox.min/js/jquery.fancybox.min.js' [] []
[2021-05-18 12:17:19] main.CRITICAL: Unable to resolve the source file for 'frontend/Vendor/Theme/sv_SE/js/jquery.fancybox.min/js/jquery.fancybox.min.js' [] []

I would really appreciate is someone could be kind and shed some light on this.

Thank you

    Can you share the relevant requirejs-config file(s) please?

    Damn, I was hoping to see an obvious issue there but it appears to be ok

  • @Alldo, Try to move fancy box js in Magento_Theme directory and then replace paths line: "fancybox":"Magento_Theme/js/jquery.fancybox.min". Exact path for move fancybox js: Magento_Theme/web/js/jquery.fancybox.min.js

  • Is it possible that you have Minify JavaScript Files configured differently for certain stores?

Include your module name in the path:

paths: {
    'fancybox': 'Vendor_Theme/js/jquery.fancybox.min'

An example from core code: https://github.com/magento/magento2/blob/2.4-develop/app/code/Magento/Cookie/view/base/requirejs-config.js#L8

var config = {
    paths: {
        'jquery/jquery-storageapi': 'Magento_Cookie/js/jquery.storageapi.extended'

Good luck!
