react-native-iap: getAvailablePurchases returning "Error: An unknown error occurred" for TestFlight build

Description

Everything was working fine with react native IAP v9.x.x with us. I updated it due to a crash issue on crashlytics regarding the thread safety. Now I am using the latest version, everything is working fine but I am not able to fetch the getAvailablePurchases in the TestFlight build. It’s working fine if I run it directly Run from Xcode.

Expected Behavior

It should return the available purchases

Screenshots

Environment:

• react-native-iap: v12.7.4
• react-native: 0.69.0
• Platforms (iOS, Android, emulator, simulator, device): iOS

To Reproduce Steps to reproduce the behavior:

1. Call getAvailablePurchases function in the TestFlight build.
2. “Error: An unknown error occurred” returns.

async getAvailablePurchases() {

      const availablePurchases = await RNIap.getAvailablePurchases()
      Utils.log('Store All Time Total Purchases ' + availablePurchases)

      availablePurchases.forEach(element => {
        const txnMomentDate = moment(Number(element.transactionDate))
        const currentDateMoment = moment()
        const olderDays = Math.ceil(moment.duration(currentDateMoment.diff(txnMomentDate)).asDays())
        Utils.log('Transaction old days ' + olderDays)

        if (olderDays <= 35){ // #Warning: Only considering a month old txn. Need to change this if we have yearly subscription
          purchasesNeedsToCheck.push(element)
        }
      });

      Utils.log('Total Purchases needs to check ' + purchasesNeedsToCheck)

      var response = []
      for (const i in purchasesNeedsToCheck) {
        const purchase = purchasesNeedsToCheck[i];
        
        if (Utils.isSubsProduct(purchase.productId)) {
          Utils.log('Calling Validating purchase for productID : ' + purchase.productId)
          const result = await this.storeTransaction(purchase)
