Solving internally via support ticket, will update with resolution here

Also seeing this while testing, app fails to launch and gets stuck on this:

Responded in wrong window, apologies.

Same error is happening to me.

I am developing with expo.

It work in a real device but it doesn’t work in a simulator.

And I found  a following post.

https://www.delasign.com/blog/xcode-store-kit-fix-finance-authentication-error/

But it's difficult to adapt it because the construction is totally different.

Same error is happening to me.

I am developing with Swift, RevenueCat version 4.39.0 and Xcode version 15.0 (15A240d)

Suddenly I see the same. Or rather, I’ve seen the same error for ages, but it hasn’t been a problem and I’ve always assumed it’s related to running my app from Xcode (on a device though). Today the whole app loading seems to freeze for 10 seconds or so causing my other HTTP loads to time out. I’ve cleaned the build cache and restarted the phone.

Will this get fixed or should I start learning StoreKit myself?

• iOS 17.4.1
• iPhone 15
• RevenueCat 4.40.0
• Xcode 15.3

Was there ever a solution to this?

I’m receiving a similar error: 

dStoreKit] Error enumerating unfinished transactions: Error Domain=ASDErrorDomain Code=500 "(null)" UserInfo={NSUnderlyingError=0x60000151e220 {Error Domain=AMSErrorDomain Code=2 "Finance Authentication

...

There’s a similar thread here

My stack is React Native and Expo. I am not using StoreKit and have a correctly configured In-app purchase key and can successfully test sandbox purchases on a real device via Expo but not within the simulator. Is there a documented solution for this?   

Hi @brohemian, we recommend testing with a physical device as simulators can sometimes have trouble testing purchases. On the simulator are you making sure to login to a valid Apple sandbox tester account? 

@Haley Pace, yes I’m using a valid sandbox account and have verified this with successful purchases via a physical device. It would be great if we could also do this via a simulator but it seems the infinite purchase loop is still an issue. 

Hi, thanks for letting me know. Let me check with the team to see if there is any other way to fix this.

I don’t see a posted solution here, and this is the first hit on RC when I post the above error, so I’ll share what I did that made this work: I only get this on the simulator, not on an actual device.  If you, like me, are getting this error, try running it on a physical device rather than the simulator.
