StoreKit

[saroar]

how do StoreKit work I am implement same like isowords but I never get call my .paymentTransaction(.updatedTransactions(transactions))

public struct StoreKitLogic<State>: ReducerProtocol {
  @Dependency(\.storeKitAPIClient) var storeKitAPIClient
  @Dependency(\.storeKit) var storeKit

  public func reduce(
    into _: inout State, action: AppReducer.Action
  ) -> Effect<AppReducer.Action, Never> {
    switch action {
    case .appDelegate(.didFinishLaunching):
      return .run { send in

        try await self.storeKit.fetchProducts(["com.word300.beginner_montly"]) // I found my production it my monthly subscri

        for await event in self.storeKit.observer() {
          await send(.paymentTransaction(event)) // 👈🏼 never called
        }
      }

    case let .paymentTransaction(.updatedTransactions(transactions)): // never called 👈🏼
      return .run { send in
        let verifiableTransactions = transactions.filter { $0.transactionState.canBeVerified }
        let otherTransactions = transactions.filter { !$0.transactionState.canBeVerified }

        if !verifiableTransactions.isEmpty,
          let appStoreReceiptURL = self.storeKit.appStoreReceiptURL(),
          let receiptData = try? Data(contentsOf: appStoreReceiptURL, options: .alwaysMapped)
        {
            // update my api
          await send(
            .verifyReceiptResponse(
              TaskResult {
                try await ReceiptFinalizationEnvelope(
                  transactions: transactions,
                  verifyEnvelope: self.storeKitAPIClient.verifyReceipt(
                    VerifyReceiptInput.init(
                        receiptData: receiptData.base64EncodedString(),
                        excludeOldTransactions: true,
                        password: "passwd"
                    )
                  )
                )
              }
            )
          )
        }

        for transaction in otherTransactions {
          switch transaction.transactionState {
          case .failed:
            await self.storeKit.finishTransaction(transaction)

          case .deferred, .purchased, .purchasing, .restored:
              print(#line, #file, transaction.transactionState)
            return

          @unknown default:
            return
          }
        }
      }

    case let .verifyReceiptResponse(.success(envelope)):
      return .fireAndForget {
        for transaction in envelope.transactions
        where envelope.verifyEnvelope.verifiedProductIds
          .contains(where: { $0 == transaction.payment.productIdentifier })
        {
          await self.storeKit.finishTransaction(transaction)
        }
      }

    case .verifyReceiptResponse(.failure):
      return .none

    default:
      return .none
    }
  }
}```

I am so confuse https://github.com/pointfreeco/isowords/blob/main/Sources/AppFeature/StoreKitCore.swift#L38
why response is VerifyReceiptEnvelope not AppleVerifyReceiptResponse ? 1st time I m implement Store kid and I m stuck more then week
also when send this to my server to get back receipt I am getting this
21002 - The encoded receipt passed in to the requestBody’s receipt-data property is malformed
