[SERCHAT]

Hello iam new in react native and i want to log some purchases on fireabase analytics dashboard. Iam usin your awesome library to implement firebase in my react native app. I am using this code piece to log event on firebase but i cannot see the items.

` const ticketItems = new Array<FirebaseAnalyticsTypes.Item>()

        if (reservationResponse?.tickets != undefined) {

            for (const ticket of reservationResponse?.tickets) {
                const _ticket = {} as FirebaseAnalyticsTypes.Item


              

                _ticket.item_id = ticket.id.toString()
                _ticket.price = (ticket.price === null || ticket.price === undefined) ? 0 : ticket.price?.value
                _ticket.item_name = event.title.substring(0, 100)
                _ticket.quantity = 1
                ticketItems.push(_ticket)

            }

            const purchaseEventParams = {} as FirebaseAnalyticsTypes.PurchaseEventParameters
            purchaseEventParams.currency = zoneConfig.currency.code
            purchaseEventParams.value = reservationResponse.payment.total.value
            purchaseEventParams.items = ticketItems
            purchaseEventParams.transaction_id = reservationResponse.payment.config.transactionIdentifier

            await analytics().logPurchase(purchaseEventParams)
                .then(() => {
                    // LOG([`sended to firebase purchase with params : `, purchaseEventParams])
                })
                .catch((err) => {
                    LOG([`something went wrong whne log purchasement on firebase`])
                })

        }`
        
        but i can not see items on dashboard. Here is an image taken from firebase console that explain the situation

     Please tell me what is my wrong. Thanks....
