Resolving Theme 404 Errors After a Shopware Update

This community discussion on the Shopware forum highlights a common issue encountered after updating a Shopware store: a 404 error related to the all.js file. The original poster, code.bach, reported receiving a theme/4dfab05e0110e4a3ee63c438d92e87d0/js/all.js net::ERR_ABORTED 404 (Not Found) error after updating their Shopware instance and running ./bin/build-storefront.sh. They also suspected that their custom JavaScript files were not functioning correctly due to this problem.

Max_Shop responded, pointing out that all.js should not exist in Shopware 6.6+ versions. They suggested that the file might be hardcoded within the theme being used. Max_Shop provided a link to the Shopware changelog, specifically referencing the removal of all.js in Shopware 6.6.0.0, which introduced asynchronous JavaScript loading.

The relevant section of the changelog states:
