Invalid forum id

Error message

Invalid forum id '${fid}'

What it means

Thrown as an `InvalidParameterError` when the `id` path parameter (forum ID) for the People's Daily message board (领导留言板) route does not match the regex `/^\d+$/`. The forum ID must be a string of one or more digits only. The `fid` is used directly in API requests to `liuyan.people.com.cn`.

Solutions

1. Find the numeric forum ID from the corresponding person's page URL on liuyan.people.com.cn.
2. Ensure the ID is purely numeric (digits only).
3. Use the documented example `/people/liuyan/539` as a format reference.

// Validate forum ID is numeric before use
if (!/^\d+$/.test(fid)) {
    throw new InvalidParameterError(`Invalid forum id '${fid}'. Must be numeric.`);
}

function isValidForumId(fid: string): boolean {
    return /^\d+$/.test(fid);
}

When it happens

Trigger: Requesting `/people/liuyan/<id>/<state>?` with an `id` containing non-digit characters (letters, symbols, spaces, decimals). Examples: `id='abc'`, `id='539a'`, `id='53.9'`. Note: the ID should be found in the person's page URL on liuyan.people.com.cn.

Common situations: User passes a URL slug or name instead of the numeric forum ID. User includes a leading slash or other separator. The ID was extracted incorrectly from the website URL.
