flutter riverpod: how to test asyncvalue.error?

I am having trouble testing my Riverpod FutureProvider when it returns an AsyncValue.error.

I tried the test as shown below:

// Future provider  
final ipsProvider = FutureProvider.autoDispose((_) =>  IpRepository().fetchIps());

// Widget to be tested
class ExampleWidget extends ConsumerWidget {
  @override
  Widget build(BuildContext context, ScopedReader watch) {
    // hooks
    AsyncValue<List<Ip>> ips = watch(ipsProvider);
    return Container(
      child: ips.when(
        data: (data) => randomWidget,
        loading: () => progressIndicator,
        error: (_, stack) => Text('YesMan'),
      ),
    );
  }
}

// Test: I am trying to find a Text widget containing message 'YesMan'
testWidgets('ExampleWidget | error', (WidgetTester tester) async 
  await tester.pumpWidget(
        ProviderScope(
            overrides: [
              ipsProvider.overrideWithValue(AsyncValue.error('randomErrorMessage')),
            ],
            child: MaterialApp(
              home: Builder(builder: (context) {
                return ExampleWidget();
              }),
            ),
          ),
      );
      final finderError = find.text('YesMan');
      expect(finderError, findsOneWidget);
    });

I expected the test to return a text widget with message 'randomError', but instead it throws an exception as below:

══╡ EXCEPTION CAUGHT BY FLUTTER TEST FRAMEWORK The following message was thrown running a test: randomErrorMessage When the exception was thrown, this was the stack:

Any idea on how to test AsyncValue.error cases with Riverpod?

Thank you
