Error message

Invalid type: ${paramType}. Please refer to [the documentation](https://docs.rsshub.app/routes/other#${siteTitle}) for valid types.

What it means

Thrown by the 艾瑞咨询 (iresearch) report route when the `type` path/query param does not match any key in the `types` map and is not equal to any type's `label` or `value`. Plain `Error` (not `InvalidParameterError`). The message points users to the docs for the valid type list.

Solutions

Consult the route's `description`/docs (https://docs.rsshub.app/routes/other#艾瑞咨询) for the current valid type list and use one of those values.
If extending the route, add the new type to the `types` map in lib/routes/iresearch/report.ts.
Use the type's `value` or `label` (both are accepted by the fallback lookup).

Example fix

// before: GET /iresearch/report/unknownType
// after: use a documented type, e.g.
GET /iresearch/report/industry

Defensive patterns

Strategy: validation

Validate before calling

const typeObj = types?.[paramType] ?? Object.values(types).find(o => o.label === paramType || o.value === paramType);
if (!typeObj) throw new InvalidParameterError(`Invalid type: ${paramType}. Valid: ${Object.keys(types).join(', ')}`);

Type guard

const isKnownType = (t: string) => Boolean(types[t]) || Object.values(types).some(o => o.label === t || String(o.value) === t);

Prevention

Use InvalidParameterError (not plain Error) for param validation so it surfaces as a 4xx, not 500.
Surface the valid set in the error message.
Keep the types map as the single source of truth shared with the route description.

When it happens

Trigger: Request to the iresearch route with a `type` not present in the route's `types` config and not matching any `label`/`value`. E.g. `/iresearch/report/foo` where `foo` is unknown. Fires at report.ts:211 after both the direct-key and label/value fallback lookups fail.

Common situations: Typo in the type param; user references a type from outdated docs; the route's `types` map was refactored and a previously-valid type was removed.
