Error: No view found with reactTag with new architecture

[Er. Harinder Singh]

Hi there,
I am getting error No view found with reactTag but only with new architecture.
Same error in both Android & iOS.
Anyone? How to resolve it?

[Er. Harinder Singh]

I think it's because findNodeHandle is not compatible with React 18. Deprecation of findNodeHandle in React Native is similar to the deprecation of findDOMNode in React DOM.

And the thing is react-native-view-shot uses findNodeHandle

@gre make attention please.

viewRegistry[target]
is coming as null inside iOS Native Module RNViewShow.m

It looks like the native code is going to have be rewritten to support the new Fabric architecture.

It seems the following code (for iOS) needs to be written using the "Fabric Native Components" methodology:

https://reactnative.dev/docs/the-new-architecture/pillars-fabric-components

RCT_EXPORT_METHOD(captureRef:(nonnull NSNumber *)target
                  withOptions:(NSDictionary *)options
                  resolve:(RCTPromiseResolveBlock)resolve
                  reject:(RCTPromiseRejectBlock)reject)
{
  [self.bridge.uiManager addUIBlock:^(__unused RCTUIManager *uiManager, NSDictionary<NSNumber *, UIView *> *viewRegistry) {

    // Get view
    UIView *view;

    if ([target intValue] == -1) {
      UIWindow *window = [[UIApplication sharedApplication] keyWindow];
      view = window;
    } else {
      view = viewRegistry[target];
    }

    if (!view) {
      reject(RCTErrorUnspecified, [NSString stringWithFormat:@"No view found with reactTag: %@", target], nil);
      return;
    }

Hi @gre, anyone taking care of it? It's critical. Totally broken on new architecture.

[Skins App]

Any update on this one? The new architecture is a no go with this package. @gre

[Er. Harinder Singh]

We are facing this from 0.70.x. Now we are at 0.73.x and the issue is still there for new architecture. New architecture is mandatory now. Someone has to focus on this issue. React Native Skia is also capturing screenshot images. Someone can refer to the code changes from there.

@rabbitmouse

i have same issue on ios

have you found a workaround for this issue, I only found out that the addUIBlock is no longer working with the newArch enabled, i'm looking for alternatives

Here the fix for this library:

• #516

Please note that this would work only from 0.74.0-rc5 onwards (which is going to be published on Monday)
