I have created an app using React Native and am trying to create an iOS app store build through Expo's eas-cli.

When running eas build --platform ios the Fastlane build failed with unknown error

After checking the "Run Fastlane" section in the Expo build log, multiple errors are shown:

Error 1:

I am developing a RN app in Expo with firebase as backend. So far, the app only uses firebase auth and firestore and for whatever reason, I randomly started getting the error of ReferenceError: Can't find variable: IDBIndex. I adjusted my firebase config to suit the v9 standards instead of using the compat package. I ensured my app was not using Google Analytics. I have also downgraded to firebase@9.1.0 which matches up with the expo documentation and this other similar post. I have also git reverted into previous versions of the app (with earlier dependencies and code) when it was working but still got back the same error. When this occurred, I entirely reinstalled node and npm because I thought that was the only other possible reason this could be happening but that was to no avail as well (getting the same IDB error). I still think this is a firebase related issue, but I am pretty much all out of ideas as to what it could be.

Here is my firebase config:

Shaking the android device and hit Debug, and it crashes every time right away. From the Android Studio logcat, it shows No source URL loaded, have you initialised the instance?:

I started a new app using expo but when I try to open the debugger-ui with cmd-d and click on debug remote js I've got this ugly message:

I am getting this issue in react native. The things were working fine until I decicded to rerun the project doing yarn install

Here is complete error

I have tried with update expo-cli, expo-splash-screen and with cache clear command expo r -c

Let me know if there is anyone who can help.

I saw many questions on SO regarding this issue and none of them was answered (or the solution doesn't work), I don't know why. People are having this error continuously but no solution is being provided. And from past few days even I'm encountering this error (Note: It seems to be working fine on my physical device (not while debugging, it works on only if I release it), but not on android emulator, so I'm pretty sure my internet is working fine):

I am developing an app using react native, every time I refresh the app on the emulator in onAuthStateChanged and currentUser from firebase I get null.

I have read about waiting onAuthStateChanged to get a status update but I never do, so I guess I misconfigured something.

I am using expo 44, react 17, firebase 9.6.5 but in compat mode (planning in fully migrate later)

My first attempt of solution was trying to add persistence: firebase.auth().setPersistence(firebase.auth.Auth.Persistence.LOCAL);

I am trying to use createDrawerNavigator from import { createDrawerNavigator } from '@react-navigation/drawer'; in react native. However, I am getting the error below, which I don't know how to solve.

Error: Requiring module "node_modules\react-native-reanimated\src\Animated.js", which threw an exception: Error: Reanimated 2 failed to create a worklet, maybe you forgot to add Reanimated's babel plugin?

In babel.config.js I tried to add the below code but not working as well
