Unable to get Subscriptions on IOS using getSubscriptions with Storekit file

[Avamae-GarthvanBelkum]

Description

• I am building a react native app and trying to test my in app purchases using an Iphone 16 Pro emulator on xcode 16.4
• I have completed all relevant setup on AppStoreConnect
• when calling the "getSubscriptions" function, the subs array returns empty
• I also get the following error in my xcode terminal (Could not parse product: missingValue(for: [StoreKit.ProductResponse.Key.price], expected: StoreKit.BackingValue)
• I have tried manually creating a StoreKit file, as well as automatically syncing one from AppStoreConnect with no luck

Expected Behavior

• Upon creating a storekit file and linking it to the project for local testing via Product > Schemes > Edit Schemes > Run > Options I expect to see my subscriptions in my console log

Environment:

• react-native-iap: 12.16.2
• react-native: 0.73.6
• xcode: (Tried the following versions 16.0, 16.4, 26.0 beta 7)
• Platforms (iOS, Android, emulator, simulator, device): IOS Simulator

To Reproduce
Steps to reproduce the behavior:

Step 1 (Defining the function in RN App):
const initializeIAP = async () => {
setLoading(true);
try {
await initConnection();
console.log('[DEBUG] Connection now initiated - Manage Membership');
const subs = await getSubscriptions({
skus: ['MembershipTierOne', 'MembershipTierTwo'],
});
console.log(
'[DEBUG] Subscriptions successfully fetched - Manage Membership',
subs,
);
setProducts(subs);
} catch (err) {
console.warn(err);
} finally {
setLoading(false);
}
};

Step 2:

• Create a Synced StoreKit File / Or alternatively create one manually paying special attention to the product IDs

Step 3:

• Link the StoreKit file through xcode (Product > Schemas > Edit Schema > Run > Options
• Then select the relevant StoreKit file

Step 4:

• Run metro in vscode

Step 5:

• Run IOS Simulator (Iphone 16 Pro -> IOS v18.6)

Step 6:

• Navigate to relevant page and notice that the console log after "getSubscriptions" function returns an empty array

It looks like you might be using an older version of the package that’s no longer supported. Could you try upgrading to the latest supported release — currently react-native-iap@13.1.0 — and see if the issue still occurs?

Also, I noticed you may have created StoreKit configuration files, but those look like the StoreKit 1 process. Just to clarify — this library only supports StoreKit 2, so if your setup relies on StoreKit 1, that could be the cause of the problem. Could you confirm which flow you set up?

Good day, thank you for the response. I created my Storekit files through xcode both manually (through the GUI) as well as by syncing to my AppstoreConnect in app purchases configuration. I am on a managed workflow through expo which targets a fork of react native 0.73.x. I have tried updating to react-native-iap@13.0.4 as well as v14.0.1

When i comes to v14.0.1 I get an error pointing to React Natives JSI API (No member named 'setExternalMemoryPressure' in 'facebook::jsi::Object').

As for v13.0.4, I still seem to get the same error as mentioned above (Could not parse product: missingValue(for: [StoreKit.ProductResponse.Key.price], expected: StoreKit.BackingValue)

Out of curiosity, how can I validate whether I am creating a StoreKit 1 or 2 file? as from what I understand, the "price" key for an IAP usually comes from a StoreKit 1 file?

As a side note, I unfortunately cannot bump the version of React Native or the Expo SDK as this is a project my company started a few years back (and as much as I would like to bump the versions, there are tonnes of peer dependency issues that I am yet to resolve). I would also like to make it known that this is a piece of work I took over from another developer, so I am desperately trying to get any understanding to resolve my issue as I have a looming deadline coming up.

Looking forward to your response, Garth :)
