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:

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

 

This documentation link describes how to configure and use local App Store simulator (instead of actual App Store sandbox); but I need full integration test…

 

Fortunately, it works with real device (when I connect iPhone to Mac, and run it via XCode on real iPhone).

And today is Nov-18-2023, still unresolved, looks like bug from Apple.

I created this issue: https://github.com/RevenueCat/purchases-flutter/issues/875 - indeed it is not just “apple” ;)

For example, Flutter library in_app_purchase: ^3.1.1 doesn’t have such issue.

I am experiencing the same issue with Flutter 6.3.0 MagicWeather example; tried to run in XCode, and the same debug messages:
This StoreProduct represents an SK1 product, the type of product cannot be determined, the value will be undefined. Use `StoreProduct.productCategory` instead.

Hi there,

 

I’m using the react native package with Expo and I’ve got the same issue. It appears on Android / iPhone.

If I cancel the payment then the catch function is triggered and I can handle the situation.

 

But if the payment processes, I’ve got the tick from the Apple / Android payment popup. Subscription is created in revenuecat but the function never returns anything.

I’ve a “console.log(“Payment ok”); right after but it’s never executed. Neither any other code.

 

I’ve even tried on a new project with no other library installed, only revenuecat and the issue is here too.

@Cesar  do you have any idea?

 

Thanks!

 

Regards,
Alex

Purchases.purchasePackage() call doesn’t return for me either.

I use the capacitor plugin version 7.0.0.

I tried to place a breakpoint on the API methods. All of these work fine: setLogLevel, configure, getCustomerInfo.

But purchasePackage doesn’t get executed at all. It seems the problem is somewhere in the capacitor plugin.

Figured out it was reactivity issue in Vue.js, I thought that .toRaw() is reactive object method, but it is vue utility that you need to use on object.

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.



the deprated setup trick not solving this issue for the latest plugin purchases_flutter: ^5.6.5

still get error logs

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

but deprecated usesStoreKit2IfAvailable setter did resolve the issue.

 

final PurchasesConfiguration purchasesConfiguration = PurchasesConfiguration("apikey");
purchasesConfiguration.usesStoreKit2IfAvailable = true;

Hello,

 

I am using purchases_flutter: ^5.5.0.

Testing on iOS real device + Sandbox account. The function doesn't return in my case as well.

Everything seems to work smoothly, the log goes up to "PostReceiptDataOperation: Finished". But I can't seem to get the return value of ```await Purchases.purchasePackage(package);```

 

I checked the config so all keys are correctly set in RevenueCat.

 

Do you guys have any information about that ?

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.

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.

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.

@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) {

                                }
