[in app purchase] App Crashes when buying Consumable #85960
Description
What's happening?
- iOS app - Implemented in_app_purchase: ^1.0.6 with the latest version of flutter as of 6 July 2021.
- Buying only consumables.
- As soon as we call
InAppPurchase.instance.buyConsumable - app crashes with the message:
Terminating app due to uncaught exception 'NSInternalInconsistencyException', reason: 'Unsupported value for standard codec'
StackTrace

- Everything works just fine on Android.
- iOS device: iPhone 12, physical device, with iOS 14.6
- Upon further investigating the stack trace, found that the retrieveReceiptData method in InAppPurchasePlugin.m is called, it returns an error. When the error object is investigated, it is null. Therefore app crashes with message: type 'Null' is not a subtype of type 'Function'
How did I work out the issue temporarily?
In InAppPurchasePlugin.m, changed function retrieveReceiptData:
FROM:
(void)retrieveReceiptData:(FlutterMethodCall *)call result:(FlutterResult)result {
FlutterError *error = nil;
NSString *receiptData = [self.receiptManager retrieveReceiptWithError:&error];
if (error) {
result(error);
return;
}
result(receiptData);
}
TO:
(void)retrieveReceiptData:(FlutterMethodCall *)call result:(FlutterResult)result {
FlutterError *error = nil;
NSString *receiptData = [self.receiptManager retrieveReceiptWithError:&error];
if (error) {
// result(error);
result([FlutterError errorWithCode:@"Code: Could not retrieve receipt data"
message:@"Message: Could not retrieve receipt data"
details:@"Details: Could not retrieve receipt data"]);
return;
}
result(receiptData);
}
Hope there is a fix to the issue in future releases.
