Crash in iOS

[saghul]

Hey there! 👋 Long time users, first time crash reporters!

We use this package in Jitsi Meet and on our latest release (which uses version 2.3.3 of this package) I'm seeing the following crash in Crashlytics:

Does it ring a bell? I checked the changelog for all further versions, but there is no mention of a fix for this crash AFAICT.

Hi @saghul thanks for reaching out. We are looking into this and will get back to you later today with an update.

[justin-fiedler]

Hi @saghul we have not been able to reproduce the error on our end.

Following the steps below worked correctly for me both for 2.3.3 and the latest 2.6.0

• Create a new app following the official (non-Expo) tutorial for ReactNative
• Add @amplitude/react-native as described in our docs.

import * as React from 'react';
import { Button } from 'react-native';
import { Amplitude, Identify } from '@amplitude/react-native';

const amp = Amplitude.getInstance();
amp.init(API_KEY);
amp.setUserId('amp-rn-user-id');
amp.setDeviceId('amp-rn-device-id');

export function MyApp() {
  return (
    <>
      <Button  title="Log Event" onPress={() => amp.logEvent('BUTTON_CLICKED')} />
      <Button title="Set device id" onPress={() => amp.setDeviceId('amp-rn-device-id-from-button')}/>
    </>
  );
}

Could you try following the same steps and see if they work for you to help determine is this is an environment issue?

If that doesn't work could you please try to provide more information with steps to reproduce?

Thanks!

Env:

• XCode 13.1
• Cocoapods 1.11.1
• (amplitude-react-native 2.3.3 & Amplitude 8.2.0) | (amplitude-react-native 2.6.0 & Amplitude 8.5.0)

[saghul]

Will do!

Hi @saghul checking in to see if you were able to get things working on your end. Thanks!

Out of all crashes 64% were on iOS 15 and 4% in the background.

Thanks @saghul. I added a ticket in our backlog for now. Please let me know if you can recreate consistently and we will investigate further.

[saghul]

Quick update, we keep getting these and it has become our topmost crash 😢

We just started rolling out a new app version with RN 0.66, let's hope it'd ok with that one.
