## Description Changing `Vue.config` will not work with VTU2, for example ```javascript Vue.config.errorHandler = () => {}; ``` The wrapper for VTU 2 is a vue 3 application so it has independent config, so changing global config will not affect it. There is a vue 3 way to do it, but not in VTU 2. @xanf Could you please provide more context and maybe a recommended approach? I've put here what you've already mentioned in the latest Vue-3 migration call.
