The new grade-school exercise fails all tests due to the module
‘core-js/modules/es.array.push.js’ not being installed. Since I have no access to the actual machines I cannot debug any further than that; I can only assume that the download of the core-js package failed for unknown reasons (e.g. due to a malformed package or a signature mismatch). Locally, everything works great.
Can the maintainers please have a look? Thanks!
