Android

Yes

Summary

I have upgraded my react native project to expo 50 and after fixing all of the issues I am stuck on this issue which appears on the emulator after app building and bundling. After some investigation I found expo-crypto is a peer-dependency of expo-auth-session and I have used expo-auth-session in my project.

npx expo-doctor@latest
✔ Check Expo config for common issues
✔ Check package.json for common issues
✔ Check dependencies for packages that should not be installed directly
✔ Check for common project setup issues
✔ Check npm/ yarn versions
✔ Check for issues with metro config
✔ Check native tooling versions
✔ Check Expo config (app.json/ app.config.js) schema
✔ Check that packages match versions required by installed Expo SDK
✔ Check for legacy global CLI installed locally
✔ Check that native modules do not use incompatible support packages
✔ Check that native modules use compatible support package versions for installed Expo SDK

Hi there! It looks like your issue requires a minimal reproducible example, but it is invalid or absent. Please prepare such an example and share it in a new issue.

The best way to get attention to your issue is to provide a clean and easy way for a developer to reproduce the issue on their own machine. Please do not provide your entire project, or a project with more code than is necessary to reproduce the issue.

A side benefit of going through the process of narrowing down the minimal amount of code needed to reproduce the issue is that you may get lucky and discover that the bug is due to a mistake in your application code that you can quickly fix on your own.

Resources

• "How to create a Minimal, Reproducible Example"
• "How to narrow down the source of an error"

Common concerns

"I've only been able to reproduce it in private, proprietary code"

You may not have spent enough time narrowing down the root cause of the issue. Try out the techniques discussed in this manual debugging guide to learn how to isolate the problem from the rest of your codebase.

"I didn't have time to create one"

That's understandable, it can take some time to prepare. We ask that you hold off on filing an issue until you are able to fully complete the required fields in the issue template.

"You can reproduce it by yourself by creating a project and following these steps"

This is useful knowledge, but it's still valuable to have the resulting project that is produced from running the steps, where you have verified you can reproduce the issue.

I'm having this exact same issue expo-random.getRandomBytes is not available on android and it's happening on the screen where I'm using expo-auth-session
