src/utils/events.js:339
- This utils module is a default-exported class, but
src/utils/index.jsaggregates utilities viaimport * as ...and spreads named exports into theUtilsobject (used widely across the codebase). As-is,EventHelpercan’t be included via the existing pattern. Consider switching to named exports (or adding named exports alongside the default) and updatingsrc/utils/index.jsto expose it.
