# error

The error that caused the failure.

```
var error: (any Error)? { get }
```

## Discussion

The value of this property is an `NSError` that describes what caused the display layer to no longer be able to enqueue sample buffers. If the status is not [`AVQueuedSampleBufferRenderingStatus.failed`](/documentation/AVFoundation/AVQueuedSampleBufferRenderingStatus/failed), the value of this property is `nil`.
