Please note: if your lockfile contains many gems, the request to view the check results might time out due to Heroku's 30 second request limit. You will most likely see a page saying "Application error". If that happens, please try reloading once, since the caching might then have kicked in and the page can be displayed. If the error persists, please open a GitHub issue. Sorry for the inconvenience, we are working on improving this situation!
