Error message

Invalid domain

What it means

Identical guard to the Gamme category route: the tag route builds https://{domain}.gamme.com.tw/tag/{tag} and validates domain via isValidHost first. A failure throws InvalidParameterError('Invalid domain').

Solutions

1. Pass only 'news' or 'sexynews' as domain.
2. Leave domain unset to default to 'news'.
3. Extend isValidHost if a new subdomain is introduced.

Example fix

// before
if (!isValidHost(domain)) {
    throw new InvalidParameterError('Invalid domain');
}

// after
const validDomains = ['news', 'sexynews'];
if (!validDomains.includes(domain)) {
    throw new InvalidParameterError(`Invalid domain "${domain}". Valid: ${validDomains.join(', ')}`);
}

const validDomains = ['news', 'sexynews'];
if (!validDomains.includes(domain)) {
  throw new InvalidParameterError(`Invalid domain. Valid: ${validDomains.join(', ')}`);
}

const isValidDomain = (d: string): d is 'news' | 'sexynews' => d === 'news' || d === 'sexynews';

When it happens

Trigger: Supplying a domain other than the two known Gamme subdomains (news, sexynews), or a malformed/empty domain string. The tag parameter itself is not validated here — only the host.

Common situations: Typing the full hostname or URL into the domain field; guessing subdomain names; domain parameter left set to an old value after Gamme consolidated subdomains.
