Solutions

  1. Use one of: important, student, teacher, teaching, office.
  2. Omit :type to default to 'important'.
  3. Update stale feed URLs.

Example fix

// before
// /uestc/jwc/news
// after
// /uestc/jwc/important
Defensive patterns

Strategy: type-guard

Validate before calling

const JWC_TYPES = new Set(['important', 'student', 'teacher', 'teaching', 'office']);
function isValidJwcType(t: string | undefined): boolean {
  return t === undefined || JWC_TYPES.has(t);
}

Type guard

type JwcType = 'important' | 'student' | 'teacher' | 'teaching' | 'office';
function isJwcType(t: string): t is JwcType { return JWC_TYPES.has(t); }

Prevention

When it happens

Trigger: Requesting /uestc/jwc/<type> with an unsupported slug; default is 'important'.

Common situations: Slug typo; renamed category; user guessed a Chinese-to-English mapping that does not match the implementation.
