This v8 method is deprecated and will be removed in the next major release as part of move to match Firebase Web modular v9 SDK API. Please use setCrashlyticsCollectionEnabled() instead.

Hi,
in the app I'm enabling Crashlytics using:

crashlytics().setCrashlyticsCollectionEnabled(true);

Now I'm getting warning to replace setCrashlyticsCollectionEnabled with setCrashlyticsCollectionEnabled adn to use getApp:

 WARN  This v8 method is deprecated and will be removed in the next major release as part of move to match Firebase Web modular v9 SDK API. Please use `getApp()` instead.
 WARN  This v8 method is deprecated and will be removed in the next major release as part of move to match Firebase Web modular v9 SDK API. Please use `setCrashlyticsCollectionEnabled()` instead.

I'm a little bit confused with the message. I'm using setCrashlyticsCollectionEnabled aleady. And using getApp to get instance doesn't resolve the warning.

Any idea what to change?

[lorenc-tomasz]

Was thinking about something like this:

import { getApp } from '@react-native-firebase/app';
import { getAnalytics, FirebaseAnalyticsTypes } from '@react-native-firebase/analytics';
import { getCrashlytics, FirebaseCrashlyticsTypes } from '@react-native-firebase/crashlytics';

let analyticsInstance: FirebaseAnalyticsTypes.Module | null = null;
let crashlyticsInstance: FirebaseCrashlyticsTypes.Module | null = null;

export const analytics = (): FirebaseAnalyticsTypes.Module => {
  if (!analyticsInstance) {
    analyticsInstance = getAnalytics(getApp());
  }

  return analyticsInstance;
};

export const crashlytics = (): FirebaseCrashlyticsTypes.Module => {
  if (!crashlyticsInstance) {
    crashlyticsInstance = getCrashlytics();
  }

  return crashlyticsInstance;
};

but I'm getting

Failed to initialize consent: [TypeError: Cannot read property 'app' of undefined] for analytics.

I have checked and getApp() return app object.

and for crashlytics I'm getting:

 WARN  This v8 method is deprecated and will be removed in the next major release as part of move to match Firebase Web modular v9 SDK API. Please use `getApp()` instead.
 WARN  Failed to initialize consent: [TypeError: Cannot read property 'crashlytics' of undefined]

Old V8 works as expected. Any idea what I'm doing wrong? @russellwheatley or @mikehardy maybe you see the issue here?

[mikehardy]

No need for all the typing and is null or whatever, just call them inline when you need them

I mentioned elsewhere I couldn't reproduce the failure you see and that ReactNativ saw

setCrashlyticsCollectionEnabled is a property now, the message is subtely different for that one

    console.log(getCrashlytics(getApp()).isCrashlyticsCollectionEnabled);

should print true or false

[mikehardy]

@russellwheatley looks like setCrashlyticsCollectionEnabled isn't pointing at the property, while getCrashlyticsCollectionEnabled is? (for deprecation otice)

[lorenc-tomasz]

@mikehardy I got the root cause of the issue. In the project we are using babel-plugin-module-resolver and within plugin configuration we had cwd: babelrc. Switching to cwd: packagejson fixed the issue. However it was not easy to find this one line :D

Issue similar to this one: #8163

[mikehardy]

wow 🤯 that is subtle. Just read up on it:

https://github.com/tleunen/babel-plugin-module-resolver/blob/master/DOCS.md#cwd

Can you toggle that back and forth now that you have it working, and paste in the exact thing you see when you have it working with just the exception of that change? Could maybe go in a tips-n-tricks section with an "If you see ... you might need to change this..."

[lorenc-tomasz]

The only trick is that you need to rebuild the app after changing the setting, because restarting metro is not enough.

So with

[
      'module-resolver',
      {
        cwd: 'babelrc',
        root: ['./src'],
        extensions: ['.js', '.jsx', '.ts', '.tsx', '.ios.js', '.android.js'],
        alias: {
          _components: './src/components',
          ...
        },
      },
    ],

I got:

WARN  Failed to initialize consent: [TypeError: Cannot read property 'app' of undefined]
WARN  Failed to initialize consent: [TypeError: Cannot read property 'crashlytics' of undefined]

and with:

cwd: 'packagejson',

it works OK, except I see some deprecation messages, e.g. that I need to use:

WARN  This v8 method is deprecated and will be removed in the next major release as part of move to match Firebase Web modular v9 SDK API. Please use `getApp()` instead.

but getCrashlytics don't need getApp().

So in out project packagejson is OK. Based on the git history I see that .babelrc was removed as not needed. And from this point of time it was working kinda OK ;)

[mikehardy]

Thanks for this, I appreciate the extra detail, not sure if I can find a home for it directly in docs but having it fully documented here is already a help as it will be visible to others.

This:

WARN This v8 method is deprecated and will be removed in the next major release as part of move to match Firebase Web modular v9 SDK API. Please use getApp() instead.

...is true - it may be using it internally, and in a non-modular way so that it triggers the deprecation warning when there is nothing you can do about it. That's something we can look at internally. Thanks!

No problem. We are here to resolve issues and help each other if possible :)
