Error message

Bad type: ${ctx.params.type}. See <a href="https://docs.rsshub.app/routes/game#beng-huai-3-you-xi-gong-gao">docs</a>

What it means

Thrown by the Honkai 3rd (崩坏3) mihoyo route (deprecated) when :type is not a config key. Config maps slugs (e.g. activity 活动 id 174, strategy 补给 id 175) to numeric category ids appended to rootUrl. The message interpolates the bad value. Miss throws before the API call.

Solutions

Use a documented slug such as activity (活动) or strategy (补给).
Read the config map at the top of lib/routes-deprecated/mihoyo/bh3.js for all keys/ids.
If the throw passes but the list is empty, the numeric id on the bh3 portal likely changed.

Example fix

// before
GET /mihoyo/bh3/aktiviti   // typo
// after
GET /mihoyo/bh3/activity    // 活动 (id 174)

Defensive patterns

Strategy: validation

Validate before calling

const VALID = ['activity', 'strategy' /* + see config in lib/routes-deprecated/mihoyo/bh3.js */];
if (!VALID.includes(ctx.params.type)) throw new Error(`Bad type '${ctx.params.type}'. Valid: ${VALID.join(', ')}`);

Type guard

const isType = (v: string): v is 'activity' | 'strategy' => ['activity', 'strategy'].includes(v);

Try / catch

try { await fetch(route); }
catch (e) {
  if (/Bad type:/.test(e.message)) listTypes();
  else if (/Cannot read prop.*list/.test(String(e))) reportCategoryIdChange();
  else throw e;
}

Prevention

Numeric ids in config drift when bh3 reorganizes its portal.
Don't borrow type slugs from other mihoyo game routes.

When it happens

Trigger: Request with a :type not in config; config[ctx.params.type] is undefined → throw with the offending value in the message.

Common situations: Slug typo, using a type valid for another mihoyo game route (e.g. Genshin) that is not defined here, or the bh3 news portal changing its category ids.
