When attempting to pay with the codeless inapp button, the following error message is displayed.
The receipt is printed out.
What can you try on this issue?

Welcome to the Unity Forum! Has IAP worked for you in the past? Can you provide a little background and steps to reproduce? Can you show a screenshot of your IAP Button properties in the Inspector? What version of Unity, what version of IAP? What Android device are you testing on? Please show a screenshot of your Google Play developer dashboard showing this ProductID. You’ll want to ensure you follow the directions here Unity - Manual: Configuring for Google Play Store

It is an app that was previously released. As a result of testing last December, the above error came out. Request you to check.

test : Unity 2019.2.7.f2
UnityIAP Version: 2.2.5

JeffDUnity3D · January 6, 2021, 3:22pm

We are not familiar with this behavior. What changed in December? Can you confirm if you see the same problem with scripted IAP, perhaps test with the Sample IAP Project here? Sample IAP Project

This is happening to me also, I just implemented IAP a couple of days ago (from learning portal of unity) and I Get the same error or “OnPurchaseFailed: FAIL. Product: ‘noads’, PurchaseFailureReason: Unknown”

JeffDUnity3D · January 6, 2021, 11:00pm

Unknown is a separate error code UNSPECIFIED_STATE as reported in this thread. Please open a separate thread with steps to reproduce.

darkyer · January 6, 2021, 11:19pm

I understand, what I meant is that sometimes in some of the test builds I created (android) I get the “UNSPECIFIED_STATE” and sometimes the PurchaseFailureReason: Unknown". So I was guessing that maybe they are related

JeffDUnity3D · January 6, 2021, 11:57pm

Ah got it. Are you using Codeless IAP also? What version of IAP? The latest is Unity IAP Asset version 2.2.5 and In App Purchasing library 2.2.1 in Package Manager (both components are required)

darkyer · January 7, 2021, 3:24am

I’m using Unity 2019.2.2f1 IAP 2.2.5 and in packagemanager(2.2.1) I followed this tutorial:

and in the apks when you click the button the google pay starts (I have test account so I don’t pay) and the payment is succesfull and then I get:

NOTE: as far as I know, I’m not using codeless iap, but in the log apparently I’m using it

The important fact is that the app worked very well until last year.
check plz…

JeffDUnity3D · January 7, 2021, 2:48pm

You have a Codeless IAP Button in your scene so it’s initializing IAP twice. Please compare to the Sample IAP Project. You’ll want to remove Codeless components from your project.

darkyer · January 7, 2021, 11:29pm

It was because I had some products added in the cataloge + the IAP listener, I removed them, and I don’t get the codeless Init but I still get the same erros
