Solutions

  1. Use a documented slug such as tzgg or gsxx.
  2. Confirm keys against the config map at the top of lib/routes-deprecated/gov/wuhan/kjj.js.
  3. If the source page 404s, report the route as broken.

Example fix

// before
GET /gov/wuhan/kjj/tongzhi   // not a key
// after
GET /gov/wuhan/kjj/tzgg        // 通知公告
Defensive patterns

Strategy: validation

Validate before calling

const VALID = ['tzgg', 'gsxx' /* see config in lib/routes-deprecated/gov/wuhan/kjj.js */];
if (!VALID.includes(ctx.params.caty)) throw new Error('Invalid caty');

Type guard

const isCaty = (v: string): v is 'tzgg' | 'gsxx' => ['tzgg', 'gsxx'].includes(v);

Try / catch

try { await fetch(route); }
catch (e) { if (/Bad category/.test(e.message)) listSlugs(); else throw e; }

Prevention

When it happens

Trigger: Request with a slug not in config, e.g. /gov/wuhan/kjj/<unknown>.

Common situations: Slug typo, or source portal restructure removing a section so its config entry was deleted.
