const locationClient = new LocationClient({
  credentials,
  region: 'ap-south-1',
});

const params = {
  IndexName: 'placesAPI',
  Position: [-122.33, 47.6],
};

const command = new SearchPlaceIndexForPositionCommand(params);

const data = await locationClient.send(command);

Observed Behavior

When I’m trying to send a command, getting the error.

Connected these libs:

For reference, this is the code that react-native-get-random-values runs:

global.ExpoModules.ExpoRandom.getRandomBase64String(10)

And here is an Expo maintainer confirming that it works in a clean Expo project:

https://github.com/expo/expo/issues/17270#issuecomment-1498774816

So something more is needed to trigger this, maybe the Hermes thing 🤔

I think that the best way to solve this would be to provide a minimum viable test case which just calls global.ExpoModules.ExpoRandom.getRandomBase64String and submit that to the Expo team.

My fix was:

npx expo install react-native-get-random-values

In src/index.js:

import 'react-native-get-random-values';
import 'expo-router/entry';

In package.json: "main": "src/index.js"

@LinusU the fix works! Thanks so much!

@LinusU Perhaps you’d be up to moving to the expo-crypto package in https://github.com/LinusU/react-native-get-random-values as well?

@aleqsio Will do, would you mind reviewing this for me? https://github.com/LinusU/react-native-get-random-values/pull/45 🙏

For me the problem is that the segment module includes uuid.js which imports react-native-get-random-values. The segment module lists react-native-get-random-values as a peer dependency, but I had never installed it. Perhaps another module was depending on it so I did not notice. Once I added react-native-get-random-values as dependency to my project, then I get the “getRandomBase64String” error.

Doing this backwards fixed the issue for me; removing the dependency from the project and letting the peer dependency handle it. I was experiencing this error through the react-native-gifted-chat library which uses uuid -> react-native-get-random-values. Oddly, I had this dependency manually added for a while and didn’t see any issues until recently, but removing it has resolved the issue
