Unknown category: ${category}. Valid: ${Object.keys(category

Error message

Unknown category: ${category}. Valid: ${Object.keys(categoryMap).join(', ')}

What it means

Thrown at lib/routes/sjtu/cs/tzgg.tsx:109 when the `:category` path parameter does not match any key in the local `categoryMap` (valid keys: bkspy, yjspy, gjjl, djdy, txgz, zyfz, qt). It is an input-validation guard executed before any HTTP call to the SJTU CS AJAX endpoint, so no network request is wasted on a bad category. Note it throws a generic `Error` rather than RSSHub's `InvalidParameterError`, which means the framework will not map it to a clean 400 response.

Solutions

1. Use one of the seven documented keys: bkspy, yjspy, gjjl, djdy, txgz, zyfz, qt — see the route description table.
2. If maintaining the route, replace `throw new Error(...)` with `throw new InvalidParameterError(...)` so RSSHub returns a proper 400 status.
3. Check the radar source mapping (lines 92–95) to confirm which category key corresponds to the source URL you came from.

Example fix

// before
if (!cat) {
    throw new Error(`Unknown category: ${category}. Valid: ${Object.keys(categoryMap).join(', ')}`);
}

// after
import InvalidParameterError from '@/errors/types/invalid-parameter';
// ...
if (!cat) {
    throw new InvalidParameterError(`Unknown category: ${category}. Valid: ${Object.keys(categoryMap).join(', ')}`);
}

const validCategories = ['bkspy', 'yjspy', 'gjjl', 'djdy', 'txgz', 'zyfz', 'qt'];
if (!validCategories.includes(category)) {
    // do not call the route; surface valid options to the user
    return { error: `Invalid category. Valid options: ${validCategories.join(', ')}` };
}

const isSjtuCategory = (v: string): v is 'bkspy' | 'yjspy' | 'gjjl' | 'djdy' | 'txgz' | 'zyfz' | 'qt' =>
    ['bkspy', 'yjspy', 'gjjl', 'djdy', 'txgz', 'zyfz', 'qt'].includes(v);

When it happens

Trigger: Requesting `/sjtu/cs/tzgg/<invalid>` where `<invalid>` is not one of the seven enumerated category keys — e.g. `/sjtu/cs/tzgg/undergrad`, `/sjtu/cs/tzgg/bkspy/`, or any value with trailing characters, casing, or whitespace.

Common situations: Typo in the category slug from a copied URL; user guesses a category name instead of using the documented code; URL-encoding issues with the path segment.
