Description

Steps to reproduce:

1. Set up Clerk authentication in an Expo app.
2. Build a preview build (expo build:ios or expo build:android) or using EAS.
3. Attempt to use Clerk authentication in the preview build.

Expected behavior:

Clerk authentication should work as expected without errors, similar to the Expo Go or development build.

Actual behavior:

When running the preview build, a network error occurs every time while attempting to authenticate with Clerk. This issue does not occur in Expo Go or the development build.

Hi!

Sorry to hear you're running into an issue. To help us best begin debugging the underlying cause, it is incredibly helpful if you're able to create a minimal reproduction. This is a simplified example of the issue that makes it clear and obvious what the issue is and how we can begin to debug it.

If you're up for it, we'd very much appreciate if you could provide a minimal reproduction and we'll be able to take another look.

Thanks for using Clerk!

Please read the requirements in the linked doc: https://clerk.com/docs/troubleshooting/create-a-minimal-reproduction

• Is based off one of the templates above and contains a minimal reproduction or has been stripped down to the bare minimum code needed to reproduce the issue
• Is not a link of a full featured app or branch within an app were an error is occurring
