URL cannot contain whitespace

Error message

URL cannot contain whitespace

What it means

validate_url rejects URLs containing any whitespace character. Whitespace in a URL passed to the OS opener can split arguments or enable scheme confusion at the shell/browser boundary, so such URLs are refused outright.
