Error message

type not supported

What it means

InvalidParameterError thrown by the UESTC 新闻中心 (news) route when ctx.req.param('type') does not resolve to a key in the map object (academy, culture, announcement, notification). Truthiness of map[type] is checked, so an undefined key triggers the error; default is 'announcement'.

Solutions

  1. Use one of: academy, culture, announcement, notification.
  2. Omit :type to default to 'announcement'.
  3. Refresh saved feed URLs against the current route docs.

Example fix

// before
// /uestc/news/academic
// after
// /uestc/news/academy
Defensive patterns

Strategy: type-guard

Validate before calling

const NEWS_TYPES = new Set(['academy', 'culture', 'announcement', 'notification']);
function isValidNewsType(t: string | undefined): boolean {
  return t === undefined || NEWS_TYPES.has(t);
}

Type guard

type NewsType = 'academy' | 'culture' | 'announcement' | 'notification';
function isNewsType(t: string): t is NewsType { return NEWS_TYPES.has(t); }

Prevention

When it happens

Trigger: Requesting /uestc/news/<type> with a slug other than the four supported values.

Common situations: Slug typo; outdated feed URL referencing a retired slug; user misread the two-column description table.
