I just started a brand new integration. I'm seeing this on Android as well. On iOS I was able to use purchaseStoreProduct and that worked. But Android still exhibits the error. getOfferings and getCustomerInfo seem to work just fine. For now I have one package with one product in it per platform that is consumable. I have only tried this on physical devices with debug builds, no simulators or release builds.

React Native v0.74.2
Pixel 8 Android 14.0 API 34
iPhone 16 Pro iOS 18.1

Any workaround? Obviously this is a blocker...

Update: I've installed all the way back to v7.28.1 of this package (SDK version 7.12.0 on Android) and the error still occurs.

Hi, apologies for the delay. You will want to make sure that you are passing the correct arguments into purchaseProduct and purchasePackage. For getPackage you should make sure to pass a PurchasesPackage. Here it looks like you might be passing a RCTRawText, can you confirm you are passing a PurchasesStoreProduct or a PurchasesStorePackage

I am facing an issue with RevenueCat's purchaseStoreProduct method on Android. While it works correctly on iOS, attempting to use it on Android results in a Malformed calls from JS: field sizes are different error.

Environment React Native version: 0.74.3 RevenueCat SDK version: 8.8.0, 8.9.1 Platform: Android Device: Samsung Fold , Google Pixel 6

Code Snippet

const offerings = await Purchases.getOfferings(); 
// Extracting product from the offerings and passing it into the purchaseStoreProduct method

const purchaseResponse = await Purchases.purchaseStoreProduct(product);

Observations

getOfferings() and getCustomerInfo() work fine on both iOS and Android.
Only purchaseStoreProduct(product) fails on Android.
The same code functions as expected on iOS.

Error Message (Android)

Error: Exception in HostFunction: Malformed calls from JS: field sizes are different.
