For first post, please answer the questions below! ### Describe your issue in detail When I try to run “pnpm run build-core” under folder gui.ajax and then make all, seems like the project start and get error “error loading core/pydio.min.js?v=8d99e3b8bcc1269270e895514b7d9833:Pydio is not defined” from webpage, does anyone has the same issue? ### What version of Cells are you using? The latest version in main branch ### What is the server OS? Database name/version? Browser name or mobile device description (if issue appears client-side)? It’s a macOS 12.3.1, I’m using mysql 8.0.33 and chrome Version 114.0.5735.133 ### What steps have you taken to resolve this issue already? Seems like other two commands “build-libs” and “build-boot” in gui.ajax work well, but only “build-core” failed ---
