# ExtraErrorData | Sentry for Cloud Functions for Firebase

*Import name: `Sentry.extraErrorDataIntegration`*

This integration extracts all non-native attributes from the error object and attaches them to the event as extra data. If the error object has a .toJSON() method, the ExtraErrorData integration will run it to extract additional information.

```javascript
import * as Sentry from "@sentry/node";

Sentry.init({
  dsn: "___PUBLIC_DSN___",
  integrations: [Sentry.extraErrorDataIntegration()],
});
```

## [Options](https://docs.sentry.io/platforms/javascript/guides/firebase/configuration/integrations/extraerrordata.md#options)

### [`captureErrorCause`](https://docs.sentry.io/platforms/javascript/guides/firebase/configuration/integrations/extraerrordata.md#captureerrorcause)
