I hope to get some help here.
I am using M2.4.4 with Pagebuilder on the backend. But on Product Edit Detail I get lots of 404 errors with missing .map files.
How can I disable PageBuilder SourceMaps or how to generate them?
Magento doesn't generate any source map files for JS. You can ignore those errors or disable warnings in your browser. This feature needs only for debug uglified code.
