# assessmentSession(_:failedToUpdateTo:error:)

Tells the delegate that a configuration update failed.

## Declaration

```swift
optional func assessmentSession(_ session: AEAssessmentSession, failedToUpdateTo configuration: AEAssessmentConfiguration, error: any Error)
```

## Parameters

- `session`: The session that you attempted to update.
- `configuration`: The configuration that you attempted to update the session with.
- `error`: An error that describes the reason for the failure.

## Discussion

Discussion After you call a session’s update(to:) method, the session calls this delegate method if the update fails. If the update succeeds, the session calls assessmentSessionDidUpdate(_:) instead.
