Followed the setup guide and the minimal example template you provided: https://github.com/clerk/clerk-expo-quickstart

Getting this error when running npm run start in the iOS simulator.

I'm also seeing this, is it just version 2.2.6 ? Downgrading to 2.2.5 fixed the issue for me

[wobsoriano]

@mr-ryan-james @homanp can you confirm that 2.2.5 fixes the issue? I tried it locally starting from 2.1.1 - 2.2.5 and still getting it. Looks like a cache issue on my end and can confirm 2.2.5 works. We're actively investigating and will provide an update as soon as possible! Thank you

[wobsoriano]

Hi @homanp, can you set your clerkJSVersion to 5.18.0 and see if it fixes the issue? Thanks!
