resetWithError not working

Hi,

I'm trying to use resetWithError() in my app, but it doesn't show an error (see video).

https://user-images.githubusercontent.com/50664914/128355802-83cc0f8f-d8ad-4bfd-8eff-d876ad345a2c.mov

Configuration of the viewController:
```viewController = BarcodeScannerViewController()
viewController metadata = [AVMetadataObject.ObjectType.ean13]
viewController.isOneTimeSearch = true
viewController.headerViewController.closeButton.isHidden = true
viewController.headerViewController.titleLabel.text = ""
viewController.codeDelegate = self
viewController.errorDelegate = self
```

Callbacks:
```
func scanner(_ controller: BarcodeScannerViewController, didCaptureCode code: String, type: String) {
controller.resetWithError(message: "test error")
}
```

```
func scanner(_ controller: BarcodeScannerViewController, didReceiveError error: Error) {
controller.resetWithError(message: "Error")
}
```

Am I doing something wrong?
