I had the same error.
It works just fine after I ran npx expo run:android and ejected the native config. No other configuration was needed.

Any way of doing this without ejecting?

Could you share more about how to do this? Thank you!

@StrawberryChocolateFudge thank you so much for the tip! It saved my day.

@willpiam you need to run npx expo prebuild and then run your app using npx expo run:android. Take a backup of the folder before, just in case.

Is there a way of making it work without ejecting it? In modern Expo, let's say SDK 48/49?

I tried to debug what is actually imported:

import * as RSA from "react-native-rsa-native"

If I log the value of RSA, this is the output:

{"RNRSA": null, "RNRSAKeychain": null, "RSA": null, "RSAKeychain": null, "default": null}

If possible I would like to fix it and submit a PR, if someone can give some guidance

Any updates regarding the null issue without ejecting in expo mentioned by @alessandrocapra ?

[alessandrocapra]

I ended up using node-forge instead, it works very well

Alright - will look into it. Thanks.
