## Description

Allows filtering and reacting to the different types of error during capture.

### Considerations

The payload is in `event.detail.detail` (see [event format](/docs.facephi-en/sdks/sdk-web/componentes/selphi-biometria-facial/eventos.md#formato-de-los-eventos)). Terminal exceptions show an error view and close the widget after [errorTimer](/docs.facephi-en/sdks/sdk-web/componentes/selphi-biometria-facial/propiedades/errortimer.md).

The SPI codes are aligned with the table of [results](/docs.facephi-en/sdks/sdk-web/componentes/selphi-biometria-facial/resultados.md#codigos-de-error). For `ExternalCameraChangeTimeout`, see the value emitted in `code`.

## Example

```jsx
<facephi-selphi-widget
    onExceptionCaptured={(event) => {
      const { exceptionType, message } = event.detail.detail;
      console.error(exceptionType, message);
    }}
/>
```

```typescript
import { type SelphiExceptionCapturedDetail } from '@facephi/sdk-web-wc';

selphi.addEventListener('exceptionCaptured', (event) => {
  const detail: SelphiExceptionCapturedDetail = event.detail.detail;
});
```
