Item already owned error in consumable purchase

Hi there.

I'm having issues with Unity IAP when adding a new purchase on Google Play. Once tried first it did not get any callback and the purchase was not made even the promo code was correctly used and shown that the purchase had been made.

Now I can't try it again because it says I already own that item even being a consumable purchase and the IAP catalog has it recorded as consumable and the IAPButton has checked the "Consume product" checkbox.

Logcat is giving three "Already recorded transactions (transactionID)" and when trying to purchase the item again it shows an "onPurchaseFailed" "DuplicateTransaction" error.

The code has been working until added this new item ( it's recycled code from other games that still are working) and now I can't purchase these items. I was using the Uniity 1.xx IAP and some forums recommended updating to 2.2. Did it and still failed. Now I'm using 3.1 and still the same.

I'm a bit lost. Does someone have a clue?

Thanks in advance.

 

Thanks for your reply.

I am not using the Codeless version, at least as far as I know. The code is quite similar to that of the MyIAPManager script in the example project..

Code (CSharp):

1. void Awake()
2.     {
3.  
4.         var builder = ConfigurationBuilder.Instance(StandardPurchasingModule.Instance());
5.         builder.AddProduct("pack_100", ProductType.Consumable, new IDs
6.             {
7.                 {"pack_100", GooglePlay.Name},
8.                 {"pack_100", AppleAppStore.Name},
9.  
10.             });
11.         builder.AddProduct("pack_250", ProductType.Consumable, new IDs
12.             {
13.                 {"pack_250", GooglePlay.Name},
14.                 {"pack_250", AppleAppStore.Name},

So we have been using it wrong for years.. facepalm
Can´t still try the sample project.. It has lots of compiler errors using 2019.3.5f

Will try to fix it and contact you again.
Thanks a lot for your help

 

Hi.
Can not get rid of compiler errors on Sample IAP project v2. Looks like downgrading to 2019 breaks the project down...
Guess I have to delete IAPButtons and use normal buttons instead and delete the catalog and keep using the builder in code as we did. Could it be?
Thanks

 

Yes, that's what I did. It tells me that project is done in another version and downgrades it. When done all those errors in the screenshot are shown and can not be used.. I think the logic behind the myIAPController script and the one on our code is more or less the same. Even I can not see how does the sample project work I think I can learn something from it.
My question about IAPButtons and Catalog was about the other project, the one we have developed. Are they part of the codeless IAP and not necessary so we have to get rid of them and use normal buttons and the scripted builder?
Sorry I'm a bit confused of what's considered codeless and what not.
Thanks

 

Ok.
It has worked until now when has started to give the "item already owned" in consumables... Didn't know that iapButtons were part of the codeless iap, just thought it was a component to control the purchase callbacks such as onPurchaseFailed. Have been using it wrong for at least 3 years but it worked.
Will try to get rid of iapButtons and catalog and rebuild it tomorrow, this issue is giving me headache.
Will tell you. Thanks a lot for your patience and have a nice day.

 

As far as i know previous versions of the game do not have this issue. Not in the tests we did at least and nobody has complained about it in the published versions and purchases have been hundreds at this point.

This issue has appeared in the version we have built and pushed to the internal test channel for testing purposes before promoting it to production. A new purchase has been added in a very simple way and its settings and code are the same as the previous ones, configured as consumable. This version is not published yet in the production channel and the published one does not have any issue as far as we know.
Thanks

 

Hi Jeff.
I have been trying again and I'm facing a new problem.
Somehow, we are missing two files: GooglePlayTangle.cs and AppleTangle.cs. Our project was initially using Unity IAP 1.x and when upgraded to 2.2 to try to solve the duplicated transaction issue, did not either have them. When upgraded to 3.1 the note on the upgrade version said something about moving them to another folder but ( even searching for them in old backups) these files have never existed in our project.
They seem to be generated by the IAP plugin but can´t know how to generate or re-generate them.
Should I delete all the IAP section and start again from scratch?
Thanks
Edited: I have commented that part, seems to have something to do with validating receipts... We did not use it before so I think it could be ignored for now. Let's try if the new code works.

 

Hi again!
I have removed all the unity purchasing part and deleted our code related for IAP purchases to avoid compiler errors.
Enabled and installed again the unity IAP, version 2.2 ( although logcat says it's 2.3.0, weird... ) from the package manager and used the import feature from services>IN-APP Purchases. Remade all the code without catalog and IAPButtons, only normal buttons and code, just as IAP Sample v2 does.
Still receiving logcat warnings about "Already recorded transactions".

Although it initializes correctly, returns the prices of each item correctly and the buttons work, I still get the "You already own this item" error. Products are added as consumables.


I'm stuck again. Any idea?
Thanks

Code (CSharp):

1. public void InitializePurchases(){
2.  
3.         if (IsInitialized())
4.         {
5.             Debug.Log("Purchases are already initialized");
6.             return;
7.         }
8.         else
9.         {
10.             var builder = ConfigurationBuilder.Instance(StandardPurchasingModule.Instance());
11.             builder.AddProduct("pack_100", ProductType.Consumable, new IDs
12.             {
13.                 {"pack_100", GooglePlay.Name},
14.                 {"pack_100", AppleAppStore.Name},
15.  
16.             });
17.             builder.AddProduct("pack_250", ProductType.Consumable, new IDs
18.             {
19.                 {"pack_250", GooglePlay.Name},
20.                 {"pack_250", AppleAppStore.Name},
21.  
22.             });
23.             builder.AddProduct("pack_500", ProductType.Consumable, new IDs
24.             {
25.                 {"pack_500", GooglePlay.Name},
26.                 {"pack_500", AppleAppStore.Name},
27.  
28.             });
29.             builder.AddProduct("promorider", ProductType.Consumable, new IDs
30.             {
31.                 {"promorider", GooglePlay.Name},
32.                 {"promorider", AppleAppStore.Name},
33.  
34.             });
35.             //Debug.Log(builder);
36.             UnityPurchasing.Initialize(this, builder);
37.         }
38.  
39.  
40.     }

 

Ok, I used the import button because the installed version from the package manager was 2.2 and the warning was for 3.x and above versions only.
I did not upgrade to 4.0.3 because the log has 3 steps to follow and talks about files that have to be moved from one folder to another. Those files simply do not exist in my folders and I was not sure if only following the last step would work or would mess up the project more than already is.

Will remove all again and try 4.0.3.
Thanks a lot.

 

Yes, I was meaning the documentation on the right side of the package manager. . None of the files on the first and second steps are present in my project and never have been ( checked in previous backups).

Sorry, maybe I'm not explaining as clear as I thought, english is not my first language.

No, I didn´t manage to get the sample project working. Opening it with my Unity version ( 2019.3.5f) throws lots of compiler errors. Tried many times with no result. Tried copying assets to a fresh new empty project too but it didn´t work.


Will remove again all the IAP related elements and try installing the 4.03 version.

I apologize for this long thread. Thanks for your help.
