After you have added a few kata to a collection you and others can train on the kata contained within the collection.

Yep, I can see your code now.
You have a bug when the string is not empty and there are no matches for the regex. It's likely that if your code is working in VS Code you're just not testing that particular case; try running this:
lowercaseCount("ABC123!@€£#$%^&*()_-+=}{[]|\':;?/>.<,~")and seeing what happens.
Can you post your solution code here with a spoiler tag? It's hard to say without seeing your code or knowing what's different between the environments.
