[Solved] Unity Codeless IAP iOS works in a development build but not in a release build

Hello,

I'm using Unity Codeless IAP, added product IDs on Testflight and when I prepare a development build, I can see all of the subscriptions I created and normally can purchase, consume and restore it.

But when I create a release build and upload it to Testflight, I get an error:

UnityIAP UnityEarlyTransactionObserver: Request to initiate queued payments
NullReferenceException: A null value was found where an object instance was required.

This error appears, when I start the app. And when I try to purchase a product, I get a ProductUnavailable failure reason.

Has anyone faced it?

Thanks in advance.

Unity 2017.2.0p4
Unity IAP 1.18.0

Thank you for your response, JeffDUnity3D

Thousand repeated messages is caused because there were a lot of test purchases made on a device. And Unity IAP recovers them all the time. With all of their receipts.

This issue appears as from TestFlight builds, so as direct XCode builds.
And yes. Release in my case means that "Development Build" check box is disabled.

 

It happens with any type of the user. I also created a new Apple account to verify if it happens with a clean one. Just the IAP doesn't receive any products and all of them are unavailable. But if it was an Apple ID account issue, it should be reproduced in a development build on certain accounts. But it works absolutely fine on all of the test accounts. And I can get normal receipts and answers from Apple

No. It has been no load testing. We just tested it as usual. Just a lot of subscriptions were made.

 

It was working on some previous versions. But some IDs didn't work. Now all of them don't work. The issue is the same. I'll write you a private message now

 

It was working on 0.14.0. 3 of 9 were not working. And I don't know the reason why. I use IAP buttons. 1 fore restore and one for each subscription productID. Nothing was modified in IAP original code but changing PurchaseProductTo public to call it from another script.

 

Sorry for the miscommunication. In the project we have Leanplum A/B test integrated. We have multiple subscription screens. And 1 screen is under 1 cohort. And this screen has 3 subscription types. And none of them is working. It means that Unity IAP logs say that these Products are not available. Other products and cohorts were working as normal.

After an update I receive the error, which is shown in the initial post.
All of the products are available for sale. We created new products and test only them. Can it be an issue, that we had one productIDs in the beginning and then created some completely new? But the IDs in Unity and in store are identical. And Development build can subscribe normally as I wrote before

 

The problem was not in IAP. It was because of all of the Analytics systems were starting too fast and couldn't be loaded normally. One of them broke others and in the end somehow broke your IAP. It was working before, because we optimized our build loading time and in the development mode it just had enough time to load everything. I made a queue order of loading all of the managers and everything seems to be working now.
