Invalid URL: no host

Error message

Invalid URL: no host

What it means

extract_host could not find any host component in the URL: after stripping the scheme and taking the authority segment before the first '/', no usable host remained, so browser security cannot determine which site the navigation targets.

Solutions

1. Provide a URL with a non-empty host, e.g. https://example.com/page
2. Check for a scheme-only URL such as 'https://' or a leading slash where the hostname should be
