JS Engine Hermes: Typeerror: Cannot read property 'createNode' of null

[tushargoyalofficial]

We have a project over RN v0.61.5. We are using React Navigation v4. We are facing this error while using your library. Please help me out.

[nadunliyanage]

Did you find any solution for this? I am having this issue.

[PrasadGhan]

I am also facing the same issue.

[nikolai-git-house]

Me too.

[nikolai-git-house]

Any solution here?

[Nirony]

me 2, any news?

[saravanakumargn]

try to clear the cache.

npx react-native start --reset-cache

[chagai95]

getting the same error, when adding webrtc code that works on the browser... found this issue by googling the error, anyone understand it?

[tushargoyalofficial]

the solution was the correct native configuration in Java files. as mentioned in docs of the router flux

[tushargoyalofficial]

This issue comes when gesture handler is not configured correctly in the RN app for android.

[chagai95]

Can you link to these places or can I easily find them on google? I don't wanna take the wrong stuff thanks! Are you sure about this? are there any other possible reasons? I get it when I add my type script files to a non type script react native app and also when I add the generated JavaScript files from these typescript files...Thanks again!

[bona-ws]

Same issue here ... Any one know why it happens, and what is the solution ?

[grafosecondo]

+1

@tushargoyalofficial checked the the gesture handler configuration again and again

[hasgardee]

any fix?

[Divyanshu-Grover]

This is caused due to incorrect import for Easing animation. Please make sure it is added under 'react-native'. Auto importing Easing causes this error.

Deleting node_modules and running yarn(or npm install) worked for me

[Ahmed-Imam]

getting the same issue after migrating from v0.59.0 to 0.60.5, it occurs on Android only. deleting node_modules and reset cache didn't solve the issue.

"react-native": "0.60.5", "react-native-gesture-handler": "1.10.3", "react-navigation": "^3.0.9",

[mitrukahitesh]

The problem is with with react-native-reanimated. Follow the procedure as in https://docs.swmansion.com/react-native-reanimated/docs/installation/ It should work fine now. If it doesn't, try fixing react-native-gesture-handler as in https://docs.swmansion.com/react-native-gesture-handler/docs/#installation

[jdhl27]

The error is very dynamic. Check your main configuration files that everything is ok. In my case, in the .env I had an incorrect value that was needed for the state of the app.

[trinachaudhuri-ctri]

is this issue fixed, am facing the same, have tried all the above mentioned fixes but did not work

In my project it was cause by react native reanimated which i had to install while using the drawer in react navigation. All I had to do was to add reanimated's babel plugin in my babel.config file and did a cache reset to fix the error and run the app. The instructions to add the plugin and reset cache is given in this link. https://docs.swmansion.com/react-native-reanimated/docs/fundamentals/installation/

remove this one in Index.js (react native) -> import 'react-native-gesture-handler';

In my case the emulator was just not able to connect to the bundler.

Make sure adb is installed and the path variable is set up correctly. If needed, run adb reverse tcp:8081 tcp:8081 to forward the port. Sometimes it is required to edit the bundler location using Ctrl+m/Cmd+m too.

what should i do, cuz im having the same error

[strawberryCheeseCake2]

idk how it works but here's what i've tried which fixed this error (I was working on stack navigator for iOS)

1. addimport 'react-native-gesture-handler'; right after @format in index.js
2. delete node_modules
3. npm i -f
4. npm install @react-native-masked-view/masked-view -f
5. npx pod-install ios

Solution ✅

1. Make sure you added reanimated to your babel.config.js like this:

module.exports = {
  presets: ['module:metro-react-native-babel-preset'],
  plugins: ['react-native-reanimated/plugin'],
};

2. After updating your babel.config.js restart your server with the following command:

yarn start --resetCache

3. Finally, delete your App from your simulator. Then run on Android by pressing a in your terminal

I hope this helps.

[ryyvv]

Awesome, thanks!
