Unsupported region: ${region}

Error message

Unsupported region: ${region}

What it means

InvalidParameterError thrown by the Yahoo news listid handler when ctx.req.param('region') is not 'hk' or 'tw'. The listId-based endpoint is only implemented for Hong Kong and Taiwan Yahoo (the markets whose archive uses stream listIds), so other regions are rejected before getList is called.

Solutions

1. Use 'hk' or 'tw' as the region segment for the listid route.
2. For other regions, use the main /yahoo/news/:region/:category route instead.

function requireListidRegion(region: string) {
    if (!['hk', 'tw'].includes(region)) {
        throw new InvalidParameterError(`Unsupported region: ${region}. The listid route supports only hk and tw.`);
    }
}

function isListidRegion(value: string): value is 'hk' | 'tw' {
    return value === 'hk' || value === 'tw';
}

When it happens

Trigger: A request to /yahoo/news/listid/:region/:listId where region is e.g. 'au', 'sg', 'us', or any non-hk/tw value. The destructure `const { region, listId } = ctx.req.param()` reads both, then the includes() guard fires.

Common situations: Caller used the generic /yahoo/news region list on this listid-specific route; assumed listId works for all Yahoo regions; typo.
