Invalid k: k=${k}

Error message

Invalid k: k=${k}

What it means

Thrown by the MissKON 'top k days' route when :k is not one of '3','7','30','60'. It is a bare `throw new Error` (not an InvalidParameterError), so it surfaces as a generic error rather than RSSHub's structured invalid-parameter response. The route only supports four pre-defined windows that map to misskon.com/topN/ pages.

Solutions

1. Use one of the supported values: /misskon/top/3, /misskon/top/7, /misskon/top/30, or /misskon/top/60.
2. If you maintain the route, consider throwing InvalidParameterError instead of a bare Error so the response is structured.
3. Validate k in any client before constructing the feed URL.

Example fix

// before
if (!['3', '7', '30', '60'].includes(k)) {
    throw new Error(`Invalid k: k=${k}`);
}

// after — use the structured error type
import InvalidParameterError from '@/errors/types/invalid-parameter';
if (!['3', '7', '30', '60'].includes(k)) {
    throw new InvalidParameterError(`Invalid k: k=${k}. Must be one of 3, 7, 30, 60.`);
}

const { k } = ctx.req.param();
if (!['3', '7', '30', '60'].includes(k)) {
    throw new InvalidParameterError(`k must be one of 3, 7, 30, 60; got: ${k}`);
}

function isValidK(k: string): k is '3' | '7' | '30' | '60' {
    return ['3', '7', '30', '60'].includes(k);
}

When it happens

Trigger: Caller requests /misskon/top/<k> with k = '10', '100', '0', or any non-whitelisted value. The includes() check fails and it throws before fetching.

Common situations: User guesses a value (e.g. /misskon/top/10); URL builder defaults k incorrectly; user passes an empty or negative number.
