Summary: 

App Store in-app purchases not pulling correctly with promotional offer (free trial)

Description:

I am trying to offer users a free trial using RevenueCat and in-app purchases. The line of code throwing the error is:

const selectedPackage = offering.availablePackagess0]; // This is the package object
const product = selectedPackage.product; // Extract the product from the package

let discount: any = null;

if (product.discounts) {
await Purchases.restorePurchases().then((res) => {
console.log('Restore purchases:', res);
});
discount = await Purchases
.getPromotionalOffer(product, product.discountss0])
.catch((error) => {
Alert.alert(
'Error',
'An error occurred while fetching the subscription details. Please try again.'
);
console.log('Error getting discount:', error);
setLoading(false);
return null;
});
}

Specifically, the Purchases.getPromotionalOffer() is throwing the error:
Possible Unhandled Promise Rejection (id: 0): Error: The receipt is not valid.

The debug logs are showing the following:

So it has something to do with the "The receipt is not valid" error. The community forum has documentation on this issue, but none of the suggestions has proven helpful. I have checked the configurations with regard to Shared Secrets and p8 files. They seem to be in order.

Any suggestions to help solve the issue would be greatly appreciated!
