# Variable: E\_INVALID\_SCRAPPER\_CONFIG

```ts
const E_INVALID_SCRAPPER_CONFIG: CreatedException<[string]>;
```

Defined in: [batteries/tools/scrapper/exceptions.ts:22](https://github.com/NHTIO/ADK/blob/v1.20260609.1/src/batteries/tools/scrapper/exceptions.ts#L22)

Thrown when a Scrapper factory receives invalid configuration.

## Remarks

Fatal: config bugs (missing/unparseable `instanceUrl`, a bad `artifact` resolver, or an async
resolver passed to a `*Sync` factory) fail loud at factory-call time rather than at first scrape.
