If you named a smart-proxy with a name with spaces, e.g., "Azure 6 East US", the UI accepts the value, but then attempting to edit/manage the smart proxy through the WebUI fails.

The UI then links a browser to "https://foremanurl.com/smart_proxies/4-Azure%206%20East%20US%202" (Firefox displays a literal " " instead of %20)

And the following stack trace is available

ActiveRecord::UnknownAttributeError
