我一整天都在拼命想让它工作。
我有一个对象，我试图在键值上循环该对象类型为Map〈String，Array〉，从iOS应用程序发送到我的firebase函数。
我尝试循环键值并看到一个错误。奇怪的是记录值打印正确的值但赋值不起作用

export const createBooking = functions.https.onCall(async (data, context) => {
    if (!context.auth || !context.auth.uid) {
        throw new functions.https.HttpsError('unauthenticated', 'User not authed');
    }

    const groomerId: string = data.groomerId;
    const unixTimestamp: number = data.date;
    const requestedServicesDict: Map<string, Array<string>> = data.requestedServices;
    const customerId = context.auth.uid;

    const groomer = await admin.firestore()
        .doc('groomers/' + groomerId)
        .get();

    const customer = await admin.firestore()
        .doc('users/' + customerId)
        .get();

    const allServices = await admin.firestore()
        .collection('services')
        .get();

    const serviceFee: number = 5
    let servicesTotalPrice = 0
    let servicesTotalDuration = 0
    let requestedServices: Array<any> = []

    console.debug(requestedServicesDict)
    console.debug(typeof(requestedServicesDict))

    for (const [petId, serviceIdsArray] of Object.entries(requestedServicesDict)) {
        console.debug('petid')
        console.debug(petId)
        console.debug(typeof(serviceIdsArray))

        console.debug(serviceIdsArray)
        const serviceIds: Array<string> = serviceIdsArray // L42

        const pet = await admin.firestore()
            .doc(`pets/${petId}`) // // L42
            .get();

        const petWeight: number = pet.data()?.weight

        const servicesAndPricing = serviceIds.map(id => {
            const service = allServices.docs.find(item => item.id == id)
            const pricingAndDuration = groomer.data()?.servicePriceAndDuration[id]
            let price: number
            let duration: number

            if (service?.data().pricedOnPetSize == true) {
                if (petWeight <= 10) {
                    price = pricingAndDuration.extraSmallPrice
                    duration = pricingAndDuration.extraSmallDuration
                } else if (petWeight > 10 && petWeight <= 20) {
                    price = pricingAndDuration.smallPrice
                    duration = pricingAndDuration.smallDuration
                } else if (petWeight > 20 && petWeight <= 50) {
                    price = pricingAndDuration.mediumPrice
                    duration = pricingAndDuration.mediumDuration
                } else if (petWeight > 50 && petWeight <= 100) {
                    price = pricingAndDuration.largePrice
                    duration = pricingAndDuration.largeDuration

            } else {
                price = pricingAndDuration.price
                duration = pricingAndDuration.duration
            }

            servicesTotalPrice += price
            servicesTotalDuration += duration

            requestedServices.push({
                service: service,
                price: price
            })
        })

        requestedServices.push({
            pet: pet.data(),
            servicesAndPricing: servicesAndPricing
        })
    }

这是日志

编辑：调用函数的Swift代码

typealias PetId = String
typealias ServiceId = String
typealias RequestedServicesDictionary = [PetId: [ServiceId]]

func createBooking(groomerId: String, date: Date, requestedServices: RequestedServicesDictionary) async throws {
