Unknown type: ${type}

Error message

Unknown type: ${type}

What it means

Route /whu/cs/:type only accepts integer types 0–3 (学院新闻, 学术交流, 通知公告, 科研进展 per the description table). The handler Number.parseInt's the param and any value outside {0,1,2,3} — including NaN from non-numeric input — falls through to the default branch.

Solutions

1. Use one of the documented values: 0, 1, 2, or 3 (see the route description table in cs.ts).
2. Verify the exact path: /whu/cs/<0|1|2|3>.
3. If you need another category, check whether /whu/rsgis or /whu/swrh covers it instead.

Example fix

// before
/whu/cs/4
// after
/whu/cs/2   // 通知公告

const VALID = new Set([0, 1, 2, 3]);
const raw = ctx.req.param('type');
const type = Number.parseInt(raw, 10);
if (!Number.isInteger(type) || !VALID.has(type)) {
    throw new InvalidParameterError(`/whu/cs/:type must be one of 0,1,2,3 — got ${raw}`);
}

function isWhuCsType(v: unknown): v is 0 | 1 | 2 | 3 {
    const n = Number(v);
    return Number.isInteger(n) && n >= 0 && n <= 3;
}

try {
    // ...handler body
} catch (e) {
    if (e instanceof Error && /^Unknown type:/.test(e.message)) {
        return ctx.json({ error: 'Invalid type. Use 0,1,2, or 3.' }, 400);
    }
    throw e;
}

When it happens

Trigger: Caller requests /whu/cs/4, /whu/cs/abc, /whu/cs/-1, or omits the segment in a way that yields an unhandled value; Number.parseInt('abc') → NaN fails every case.

Common situations: Typo in the route path; copied an example for a different whu sub-route (e.g. swrh uses 0–2); aggregator passing an unsupported category id.
