Error message

Bad category. See <a href="https://docs.rsshub.app/routes/government#zhong-guo-zheng-fu-tu-jie">docs</a>

What it means

Thrown by the China.gov 图解 (illustrated policy) route (deprecated) when :caty is not a config key (documented: zhengce 图解政策, qttj 其他图解). The URL is built as rootUrl + cfg.link, so a miss throws first.

Solutions

Use zhengce (图解政策) or qttj (其他图解).
Verify against the config map at the top of lib/routes-deprecated/gov/xinwen/tujie.js.
If the underlying .htm page 404s, report the route.

Example fix

// before
GET /gov/xinwen/tujie/zhengcee   // typo
// after
GET /gov/xinwen/tujie/zhengce     // 图解政策

Defensive patterns

Strategy: validation

Validate before calling

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

Type guard

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

Try / catch

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

Prevention

Confirm the .htm endpoints on www.gov.cn still exist.
Validate before constructing the gov.cn URL.

When it happens

Trigger: Request with a slug outside the config map, e.g. /gov/xinwen/tujie/<unknown>.

Common situations: Slug typo, or the source site (www.gov.cn/xinwen) reorganizing the tujie section so a slug was dropped.
