If you have a stream name that has a "/" in it, you can't get to the stream on the UI.
"SomeThing/f6baee17-cf32-4c0d-bb93-5eaebd308c0d" is a stream name that I have.
If I go to the website and try to click on that stream name, it takes me to the URL:
Which gives me a 400 Bad Request
Fix should be to url encode the name and decode it on the other side.
Same issue exists for projections.
