Error throwing while upgrading expo sdk from version 40.0.0 to 44.0.0

Please provide the following:

  1. SDK Version:40.0.0
  2. Platforms(Android/iOS/web/all):all
  3. Add the appropriate “Tag” based on what Expo library you have a question on.
    Error: [@RNC/AsyncStorage]: NativeModule: AsyncStorage is null

Currently our app is running on expo sdk version 40.0.0 and trying to upgrade to the latest version of expo, during upgrading when I am running the project in android simulator I am getting following error:

Error: [@RNC/AsyncStorage]: NativeModule: AsyncStorage is null.

To fix this issue try these steps:

• Run react-native link @react-native-community/async-storage in the project root.

• Rebuild and restart the app.

• Run the packager with --reset-cache flag.

• If you are using CocoaPods on iOS, run pod install in the ios directory and then rebuild and re-run the app.

• If this happens while testing with Jest, check out docs how to integrate AsyncStorage with it:
I have tried all steps mentioned above but nothing worked, please help to resolve the issue.

Error during upgrade|690x164
I am stuck and unable to upgrade my app, please help so that I can move ahead and successfully upgrade the app.


Hey @sbi-webteam, we recommend upgrading one SDK version at a time and make sure you read about the breaking changes for each SDK. I would revert your changes to a previous commit and then go with the incremental approach.


I am doing the same my app was on version 39.0.0, I have successfully upgraded it to version 40.0.0 and now I am trying to upgrade to next 41.0.0, my goal is to upgrade it to the latest, and while upgrading I am getting the above error. Please help to that I can get rid of the error and able to upgrade my app. I have upgraded @react-native-community/async-storage to @react-native-async-storage/async-storage as well.
Currently I am trying to run my app in android simulator.


Hi @sbi-webteam

Could you show us your dependencies and some of the AsyncStorage imports and code?

Sorry for delay in reply but somehow I got success to upgrade my app into version 41.0.0 now I am moving next (42.0.0) and again I am started facing same issue, I have applied all those options that I opt to update app from 40.0.0 to 41.0.0 but still getting same error. Please review my package.json file:
