Android 12.6.1: Error: Getting '$$typeof' from binding before it was injected, js engine: hermes about realm-js

[Overtorment]

Our configuration can be found here (its FOSS): https://github.com/BlueWallet/BlueWallet

we reverted to 12.6.0
My colleague reported that he also experiensed somethign weird on iOS with 12.6.1

Interesting that our android e2e passed on CI - I suppose this is because this error is not causing a crash, just a red screen, which can be closed, and on production build its not displayed at all

[kraenhansen]

We just released v12.6.2 with a fix for this - please help us verify that this solves the issue.

And thanks again for bringing it to our attention! 💙

It seems alright for me now, i updated again and its working!

[Overtorment]

@kraenhansen just fyi, your build said its successfull, it just could notlaunch the app on the emulator. just switchto emulator and tap the icon to run the app.

i will testthis fix, thanks

Thank you for creating the issue. This is most likely related to Realm: We recently changed the way we initialise our binding to the Realm Core database and this error is thrown when this binding is accessed before it gets injected.

To help us debug this, we'd love to know more about your setup.

• Would you be able to share your babel and metro configurations?
• Are you using Expo?
• Are you able to share more of the stack when this error is thrown?

Im with the same issue, im using expo but bare-workflow and the error is thrown as soon as i open the app. Here are my babel and metro configs:

metro:
const { getDefaultConfig } = require('expo/metro-config'); module.exports = getDefaultConfig(__dirname);

babel:
module.exports = function(api) { api.cache(true); return { presets: ['babel-preset-expo'], plugins: ['react-native-reanimated/plugin'], }; };
After this error im also getting this error:

Invariant Violation: "main" has not been registered. This can happen if:

• Metro (the local dev server) is run from the wrong folder. Check if Metro is running, stop it and restart it in the current project.
• A module failed to load due to an error and AppRegistry.registerComponent wasn't called., js engine: hermes

Hi! having the same issue. Similar configuration with the difference that in the metro config we have:

const { getDefaultConfig } = require('expo/metro-config');

const config = getDefaultConfig(__dirname);

config.resolver.assetExts.push(
  // Adds support for `.db` files for SQLite databases
  'db'
);

module.exports = config;

Hey, after some investigation the problem for me was an npm upgrade that changed A LOT of dependencies versions at my package-lock.

I simply reverted the commit and npm installed again, now its working as it should.

The file is 18000 lines long so I will not be pasting it here but if yall need something also i will do what I can.

@Overtorment I tried cloning your BlueWallet repo (on the commit before downgrading Realm) but I can't get it to build on Android:

This is what I get when I open the project in Android Studio:

Null extracted folder for artifact: ResolvedArtifact(componentIdentifier=com.facebook.react:hermes-android:0.72.10, variant=com.facebook.react:hermes-android:0.72.10 variant debugVariantDefaultApiPublication, variantName=null, artifactFile=/Users/kraen.hansen/.gradle/caches/modules-2/files-2.1/com.facebook.react/hermes-android/0.72.10/39749c188b17b3722b70d1d5014ad0e64e81c26d/hermes-android-0.72.10-debug.aar, isTestFixturesArtifact=false, extractedFolder=null, publishedLintJar=null, dependencyType=ANDROID, isWrappedModule=false, buildMapping={current_build=/Users/kraen.hansen/Projects/BlueWallet/android, gradle-plugin=/Users/kraen.hansen/Projects/BlueWallet/node_modules/@react-native/gradle-plugin})

Simply running npx react-native run-android --verbose yields:

I then tried iOS but hit BlueWallet/rn-ldk#47.

I also tried an Expo app, but without success and none of our test apps display this behaviour either 🤔

I do believe to have a fix ready for this particular case (I hope to be able to merge and release this early next week), but I would love to be able to reproduce this issue to understand why it happens and verify that it's actually solved for your particular setup.
