null is not an object (evaluating 'ReactNativeExceptionHandler.setHandlerforNativeException')'

[bogdanpk]

Hi guys,

setJSExceptionHandler is working fine (without setNativeExceptionHandler) , but when I use setNativeExceptionHandler, I can't even run my app (it throw error before even starting the app):

null is not an object (evaluating 'ReactNativeExceptionHandler.setHandlerforNativeException')'

I tried to build .apk, it also doesn't work. I tested it on Android.

This is my code where I implement react-native-exception-handler

import React, { useState, useEffect } from 'react';
import { MyContextProvider } from './context/Context'
import AppStart from './AppStart'
import { Root } from "native-base";
import './i18next/i18n'
import { MenuProvider } from 'react-native-popup-menu';

import {  Alert } from 'react-native';
import { setJSExceptionHandler, setNativeExceptionHandler } from 'react-native-exception-handler';

const errorHandler = (e, isFatal) => {
  if (isFatal) {
 
    Alert.alert(
        'Unexpected error occurred',
        `
        Error: ${(isFatal) ? 'Fatal:' : ''} ${e.name} ${e.message}
        We have reported this to our team ! Please close the app and start again!
        `,
      [{
        text: 'Close'
      }]
    );
  } else {
    console.log(e); // So that we can see it in the ADB logs in case of Android if needed
  }
};

setJSExceptionHandler(errorHandler, false);

 setNativeExceptionHandler((errorString) => {
   console.log(errorString);
}, false,); 

export default function App() {

  return (
    <MyContextProvider>
      <Root>
        <MenuProvider>
          <AppStart />
        </MenuProvider>
      </Root>
    </MyContextProvider>
  );
}

Any help?

Thank you

Getting this kind of issue with 'react-navigation' version 5. Do you guys need more details?

Any solution for this? I have the same problem.

Hi Josema, Unfortunately, I didn't solve the issue.

We also encountered this problem, any idea?

[salhotra]

You'll see this if the library is not linked natively. Make sure to link it and rebuild the app

[OoDeLally]

Same here

[MCervenka]

Same here. Autolinking is not working or something

Don't forget to run pod install!
