Error message

Bad category. See <a href="https://docs.rsshub.app/routes/government#zhong-qing-shi-ren-min-zheng-fu-liang-jiang-xin-qu-xin-xi-gong-kai-wang-zheng-wu-gong-kai">docs</a>

What it means

Thrown by the Chongqing Liangjiang New Area government-affairs-publicity route (deprecated) when the :caty segment is absent from the config map. The handler resolves a URL from config[ctx.params.caty]; a miss throws a plain Error pointing at the docs anchor. No fetch occurs before the check.

Solutions

  1. Use a documented slug such as zcwj (履职依据) or gsgg (公示公告).
  2. Read the config map at the top of lib/routes-deprecated/gov/chongqing/ljxq/zwgk.js for the authoritative key list.
  3. Prefer a non-deprecated equivalent route if one exists.

Example fix

// before
GET /gov/chongqing/ljxq/zwgk/zwwj   // wrong slug
// after
GET /gov/chongqing/ljxq/zwgk/zcwj    // 履职依据
Defensive patterns

Strategy: validation

Validate before calling

const VALID = ['zcwj', 'gsgg' /* + see config in lib/routes-deprecated/gov/chongqing/ljxq/zwgk.js */];
if (!VALID.includes(ctx.params.caty)) throw new Error('Invalid caty');

Type guard

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

Try / catch

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

Prevention

When it happens

Trigger: Requesting the route with a category slug not defined in config (e.g. zcwjy, gggs misspelled). config[ctx.params.caty] is undefined and the throw executes.

Common situations: Slug typo, using a category from a sibling Chongqing route that does not apply here, or stale docs after a site restructure of the Liangjiang portal.
