React native required dispatch_sync to load

[LukePenkava]

Hi, i am getting this error once in a while when reloading React Native app. No idea, if that is something on my side or what to do with it. But i think that this error has something to do with navigator.geolocation.getCurrentPosition(). Not sure tho. Thanks for any help.

react native required dispatch_sync to load constants for RNGestureHandlerModule. this may lead to deadlocks

Is it an error or showing as a warning?

I started getting this as well. It's a warning (yellowbox). Any idea what it means?

[msageryd]

I have seen it occasionally before. But after upgrading from 1.3.0 to 1.4.1 I get it on every app-start in the simulator.
@SnehalAgrawal It's a warning.

edit: I'll take it back. It's not every start, but most.

Any fix?

2021 and still have this warning on iOS. I am using react-native: 0.60.6 and react-native-gesture-handler: 1.10.3

This error showed up for me the very first time after upgrading expo sdk to verison 44. (RNGH v2)

Same error for me, seemed to appear after upgrading to RNGH v2

I've upgraded to RNGH 2.1.0 - but the error still remained. I've checked the docs once again, and found that we should wrap our app with a GestureHandlerRootView since 2.0.0.

So what I changed

import 'react-native-gesture-handler';
import { GestureHandlerRootView } from 'react-native-gesture-handler';
....

  return (
    <DripsyProvider theme={colorMode === 'dark' ? theme : themeLight}>
      <QueryClientProvider client={RNQueryClient}>
        <SafeAreaProvider initialMetrics={initialWindowMetrics}>
          <GestureHandlerRootView style={{ flex: 1 }}>
            <Navigator theme={combinedTheme} />
          </GestureHandlerRootView>
        </SafeAreaProvider>
      </QueryClientProvider>
    </DripsyProvider>
  );

After wrapping with GestureHandlerRootView, the warning disappeared for me and never returned, even after 40 App restarts.
The only thing I am unsure about is the fact that I have to import rngh and import GestureHandlerRootView. Do I still need to import it that way?

I'm wrapping the view, yet I keep getting the same warning. Thoughts?

[hirbod]

I did not dig into it. At least the warning did disappear for me after wrapping it with the RNGHRootView.

At the end, it’s just a warning and we could add an exception to yellow box to get rid of it.

Edit: after couple of restarts, it did appear again for me as well. So my provided "solution" isn't one.
