Question

Purchases.purchasePackage() doesn't return

Hello,

I’m using purchases-flutter 4.1.2 (latest at the moment). I’ve set up the entitlements, offerings, products as well as packages as guided in https://docs.revenuecat.com/docs/ios-products

I can get the offerrings and display the packages correctly.

But when I make a call to `Purchases.purchasePackage()` to purchase a package, the call just hangs and doesn’t return at all.

Here’s my dependency list:

```

And this is the debug log when I try to load the screen and trigger the purchasePackage function:

Thanks for opening this question with more details. One quick question. Does this happen to you only on iOS? Have you tried on an Android device?

Are you running on a physical device or a simulator?

Thanks!

Hi @Cesar, I’m experiencing this on iOS only. I haven’t been able to test this on Android yet.

I tried on both physical iPhone and simulator, both stuck after tapping the package (which triggers the purchase function).

Getting same error on IOS Device at the same place as the poster (also not using android):

[Purchases] - WARN: 🍎‼️ There is a problem with the SKPaymentTransaction missing a transaction date - this is an issue with the App Store. Unix Epoch will be used instead.

I’m using flutter and had the following code:

await Purchases.setup("blahblahblah",    appUserId: LoginUser.userUid);

which was showing as deprecated.

So I updated to the new format found on the revenuecat website:

 await Purchases.configure(     PurchasesConfiguration("blahblahblah")       ..appUserID = LoginUser.userUid

and got the above error. 

Reverted back to the deprecated code and its working ok.

Hi @Thanh !

We are trying to reproduce the issue. As @Andy suggested in the GitHub issue, we're currently preparing release 4.2.0, which will get rid of the warnings you see on the console and might also fix the issues, since it uses StoreKit 2 APIs under the hood, and they seem to be more reliable.

Are you also handling errors? Do you see any PlaformException at all?

My mistake, I didn’t add the Appstore shared secret to Revenuecat. After I did, the function doesn’t hang on my real iPhone, but it still hangs on the iOS simulator.

@Cesar Thank you for the update. I’m eager to try out the new release ^^

Are you also handling errors? Do you see any PlaformException at all?

 

Yes I have try & catch block to handle the exception but there’s no exception thrown at all because the function purchasePackage doesn’t return.

Here’s my code:

                              try {
                                final CustomerInfo customerInfo = await Purchases.purchasePackage(packages![selectedPackageIndex!]);
                                final isPremium = customerInfo.entitlements.all[REVENUE_CAT_DEFAULT_ENTITLEMENT]?.isActive ?? false;
                                if (isPremium) {
                                  // Display flashbar and go back
                                }
                              } on PlatformException catch (e) {
                                final errorCode = PurchasesErrorHelper.getErrorCode(e);
                                if (errorCode != PurchasesErrorCode.purchaseCancelledError) {
                                  print(e);
                                }

but it still hangs on the iOS simulator.

 

That’s probably because iOS simulators require a special configuration using StoreKit config files. You can read more about that in this article in our docs https://docs.revenuecat.com/docs/apple-app-store#ios-14-only-testing-on-the-simulator

Do you mind giving that a try and report back?

The fact that purchasePackage doesn’t return is indeed a weird one, because I would expect it would throw an error indicating there’s a problem with your configuration in RevenueCat. We’ll look into that

Hi Cesar, I haven’t tested on simulator as you said (using storekit config file) yet. Other than that the function does return on real iphones after setting Appstore shared secret.

Hi @Thanh, when you tried this on physical device, are you using sandbox tester account or the real apple account ?

In my case this issue appears only on iOS. On Android everything seems to work fine. Now on iOS, I have two subscriptions. An annual and a monthly. The annual one, works fine. But when a user chooses the monthly, I’m getting the following warning:

This StoreProduct represents an SK1 product, the type of product cannot be determined, the value will be undefined. Use `StoreProduct.productCategory` instead.

Does your `purchasePackage` function also not return? Is anything not working?

Those warnings are just indicating that the product’s productType will be `nonConsumable` because it can’t be determined and that should be accessing `productCategory` instead, so they should be safe to ignore. I think we will probably update that log since it’s clear it’s too noisy.
