NullReferenceException at UnityEngine.Purchasing.StandardPurchasingModule.Configure ()

Hello! We are using Unity 2017.4.7f1 and Unity IAP 1.20.0. We have our custom PurchasingModule implementing AbstractPurchasingModule for WebGL and Steam. WebGL module works fine, but we have this error with Standalone target for Steam build:

Code (CSharp):

1.  
2. NullReferenceException: Object reference not set to an instance of an object
3.   at UnityEngine.Purchasing.StandardPurchasingModule.Configure () [0x001f9] in <5c8e2bc39ab0483c8e6057a26f636afa>:0

6.  

This error starts at:

var builder = ConfigurationBuilder.Instance(new InHousePurchasingModule(), standardPurchasingModule);

With some previous Unity IAP (can't tell exact version) it worked fine.

 

I have the same error with Steam. I'm using Unity 2017.3.0f3 and Unity IAP 1.20.0.

Code (CSharp):

1. NullReferenceException: Object reference not set to an instance of an object

Code (CSharp):

1. builder = ConfigurationBuilder.Instance(new SISPurchasingModule(), StandardPurchasingModule.Instance());

 

Can you provide steps to reproduce when building for Steam? Is this Windows exe standalone?

 

In my case yes, this is Windows exe standalone. Your Unity IAP 1.18.0 uploaded version help me. Now it works like a charm!

 

Yes, like in mr-euksinus's case, it happens on Standalone Windows target.

 

@reflexing What store are you targeting? Can you provide steps to reproduce (building for Steam)?

 

There must have been a change in either Unity IAP 1.19 or 1.20, since 1.18 works correctly when initializing two modules at the same time.

Unity IAP 1.18, all platforms. Unity 1.20, all platforms except Standalone:

Code (csharp):

1. var builder = ConfigurationBuilder.Instance(new InHousePurchasingModule(), standardPurchasingModule);

Unity IAP 1.20, Standalone:

Code (csharp):

1. var builder = ConfigurationBuilder.Instance(new InHousePurchasingModule());

Basically having two modules in Unity IAP 1.20 on Standalone is broken. Going to submit a bug report for this later on, because several users of our Simple IAP System asset ran into this already.

 

@Baroni Can you open a new forum thread for this new issue?

 

It is the same issue. The NRE is coming from that. Only having one module is not causing the NRE.

 

@Baroni Understood, thanks for confirming

 

I have not been able to reproduce. However, my test may not be valid because I'm simply declaring StandardPurchasingModule twice, I'm not testing with a real implementation. Can you confirm the behavior when you do the same?

var builder = ConfigurationBuilder.Instance(StandardPurchasingModule.Instance(), StandardPurchasingModule.Instance());

 

One year later.. Was it solved? Have same issue with subscription. Using latest Unity personal. Google play app published subscription setup. In editor
ProcessPurchase: PASS. Product: 'single_site'
UnityEngine.Debug:Log(Object)
When running on fevice or standalone development build NullExeption error Object reference not set to an instance... UnitiEngine.Purchasing.StandardPurchasingModule.Configure()

 

@Vanabee please show the code you are using and the logs from the device when the issue occurs. What version of IAP are you using?
