Invalid region

Error message

Invalid region

What it means

The eprice RSS route targets regional eprice domains and restricts the `region` path parameter to an allowRegion Set containing only `tw` and `hk`. Any other value (or a value that bypasses the default) throws InvalidParameterError before the RSS fetch.

Solutions

1. Use `tw` (default) or `hk`.
2. Omit the region segment to fall back to `tw`.

Example fix

// before
//   /eprice/sg
// after
//   /eprice/tw

const allowRegion = new Set(['tw', 'hk']);
function isValidRegion(region: string): boolean {
  return allowRegion.has(region);
}

function isValidRegion(region: string): region is 'tw' | 'hk' {
  return region === 'tw' || region === 'hk';
}

When it happens

Trigger: `/eprice/<region>` where <region> is not exactly `tw` or `hk` — e.g. `/eprice/sg`, `/eprice/cn`, `/eprice/HK` (case-sensitive).

Common situations: Guessing a region code; supplying an uppercase variant; passing a country code for a region eprice does not serve.
