Update to 2.2.2, have some NullReferenceException

umiringo73 · Nov 27, 2020

Hi,
I update Unity IAP to 2.2.2 recently and without any code changing of my IAP logic.

But when I check the cloud diagnostics, I found some nullreferenceexception.

May I know whether it is a issue?

Call stack is

UnityEngine.Purchasing.Models.GooglePurchaseResult.FillPurchases (UnityEngine.AndroidJavaObject purchaseResult, Stores.IGoogleCachedQuerySkuDetailsService cachedQuerySkuDetailsService) (at <00000000000000000000000000000000>:0)

Same issue here after the update

JeffDUnity3D · Nov 30, 2020

Is this during IAP initialization or during a purchase?

Hi
According to the callstack, It happens not in init or purchase.
I check user's subsricption infomation every hour in OnApplicationPause when pause is false, in case user's subscription changed.
it should happened when I query the subscription info.

That's the problem. We can't reproduce the bug on any of our devices during QA. Those crashes are from Firebase Crashlytics of a released game.

Unfortunately there is no action we could take in that case. You would want to look for any specifics around the crash reports, like the same phone type, country, etc. Otherwise you'll want to publish with Unity 2.2.4 (or the most current version, they are coming out fast) and see if it helps.

vidra · Dec 9, 2020

The problem started appearing in crashlytics when I upgraded the unity package from 2.1.1 to 2.2.0.
The current build is live with version 2.2.4. It still happens.
Thinking about reverting back.

We are checking. If you can find steps to reproduce, it would be appreciated. But we will inspect the code regardless.

Jeff, I have a project where I can stably reproduce this case. I'd like to strip down all assets/code, pack it and send it to you. Should I use PM here or would you like me to send it via e-mail?

Please provide your project, unless you can identify any differences between the Sample IAP project. Please DM me

Hellfim · Dec 11, 2020

Well, actually I've managed to reproduce it on the Sample IAP project. You just need to update Unity IAP to the latest version (but I guess v2.2.0 is the broken one), then build and viola - the exception is there. I also added Unity-Logs-Viewer plugin to the project to check logs on the device, but that shouldn't be a problem.

I guess it somehow might be related to the device operation system or smth. My test cases were:
Alcatel 4047D with Android 7.0, gsm MT6580M, kernel 3.18.35+, build 010 05
Xiaomi Mi 6 with Android 9 PKQ1.190118.001 MIUI Global 11.0.6.0 Stable (PCAMIXM), gsm AT20-0307_2204_3754711, kernel 4.4.153-perf+

Sorry, I don't understand your voila comment, might you be able to elaborate? When do you get the error? Are you making a purchase? Is it during initialization? What type of product if purchasing? I am able to purchase a consumable, non-consumable and subscription without the error, with the Sample IAP project using my Samsung Galaxy S7. Please provide your steps to reproduce.

Hellfim · Dec 11, 2020

Sorry, my bad I didn't explain it through.
You just need to launch a build. The exception appears after initialization is complete. There is no need to press any buttons.

That screenshot doesn't show initialization as completed, it crashes the app prior to that? Please add additional MyDebug statements to see exactly where it is. Also, please show your products as listed on the Google play store and defined in the app. Do they all have a Description? Also, please provide the full adb logcat logs as an attachment. We have a good idea where in the code the issue might be, but we need steps to reproduce so we can confirm and test a potential fix.

I'm using Sample IAP without any changes, so I guess it should be set up.

Anyway, I guess I've found the problem (or a clue for you) - exception appears when I make a build with Unity 2019.2.1f1, and it works fine in the 2020.1.2f1. Hope that helps.

Unfortunately it doesn't help. We are not able to reproduce here with the steps you've mentioned. Can you provide the information I requested? And your "guess that it should be set up", you would need to have created the same products on your developer Dashboard, did you do this? Please show a screenshot of your Google dashboard where you have defined the products for the Sample IAP project such as "noads" and "gold50" with the full steps mentioned here https://docs.unity3d.com/Manual/UnityIAPGoogleConfiguration.html In your own Google Developer Dashboard at https://play.google.com/apps/publish , be sure to add a Description for your products, perhaps we have an issue with a missing field. Hmm, I'm not able to blank out the Description field on my dashboard, so apparently it's not that since it's a required field.

Hellfim · Dec 11, 2020

Where do you want me to put additional debug messages? It seems that exception happens somewhere in the internal initialization. If I comment out UnityPurchasing.Initialize(this, builder); then there is no exception, if I leave it as is exception appears right after game launch.

And your "guess that it should be set up", you would need to have created the same products on your developer Dashboard, did you do this?
Click to expand...

No, I did not. And services for the project ain't set up either. Although Unity IAP shouldn't throw exceptions, instead it should throw OnInitializeFailed shouldn't it? The exception appears on both signed and unsigned versions by the way.

I can't setup a different project in the Dashboard right now. I'm sure that my live project is correctly set up there as it works fine with v2.1.1 and breaks with the v2.2.0.

I'm attaching a Sample IAP project (without any set up, yet it shouldn't throw exceptions) with the problem below

We believe you! We are not saying that your project is not correctly set up. Of course it shouldn't throw exceptions, we are trying to fix that, no argument there. There looks like there is indeed an issue. But we need steps to reproduce here so that we can test any potential fix we might want to release. We are looking to see why you can reproduce and we cannot, so we are looking for differences, and why I ask you provide the information requested. Please show a screenshot of your Google Dashboard products so we might compare. The sooner you can provide this information, the sooner we can fix it! Also, what version of Unity are you using? Since it happens without any products configured, it likely ISN'T in your dashboard, but we need to rules things out. I'm using Unity 2020.1.6f1 here.

JeffDUnity3D · Dec 11, 2020

I also see the exception in your APK when I install it. When I build the Sample IAP project here, I don't see it. What version of Unity are you using? Also, what version of IAP? In the Editor, use menu Window/Unity IAP/IAP Updates. Also, what version of the In App Purchasing library in Package Manager?
