Swift 数据无法’；因为它是’；t格式正确

我正在尝试使用Stripe和Firebase在IOS应用程序中创建

StripeEphemeralKeys

，但当我尝试打印数据时，总是出现此错误<代码>无法读取数据，因为它的格式不正确。我不知道为什么

功能：

exports.createStripeEphemeralKeys = functions.https.onCall((data, context) => {
const customerId = data.customerId;
const stripe_version = data.stripe_version;
return stripe.ephemeralKeys
    .create({
        customer: customerId,
        stripe_version: stripe_version
    })
});

func choosePaymentButtonTapped() {

    guard let uid = Auth.auth().currentUser?.uid else { return }

    var paymentContext: STPPaymentContext?

    let ref = Database.database().reference().child("stripe_customers").child(uid)
    ref.observeSingleEvent(of: .value) { (snapshot) in

        guard let dict = snapshot.value as? [String: Any] else { return }
        guard let customerId = dict["customer_id"] as? String else { return }

        let customerContext = STPCustomerContext(keyProvider: StripeProvider(customerId: customerId))
        paymentContext = STPPaymentContext(customerContext: customerContext)
        paymentContext!.delegate = self
        paymentContext!.hostViewController = self
        paymentContext!.presentPaymentOptionsViewController()
    }
}

class StripeProvider: NSObject, STPCustomerEphemeralKeyProvider {
lazy var functions = Functions.functions()
let customerId: String

init(customerId: String){
    self.customerId = customerId
}

func createCustomerKey(withAPIVersion apiVersion: String, completion: @escaping STPJSONResponseCompletionBlock) {
    let data: [String: Any] = [
        "customerId": customerId,
        "stripe_version": apiVersion
    ]
    functions
        .httpsCallable("createStripeEphemeralKeys")
        .call(data) { result, error in

            if let error = error {
                print(error.localizedDescription)
                completion(nil, error)
            } else if let data = result?.data as? [String: Any] {
                completion(data, nil)
            }
    }
}
}

演示文稿：

exports.createStripeEphemeralKeys = functions.https.onCall((data, context) => {
const customerId = data.customerId;
const stripe_version = data.stripe_version;
return stripe.ephemeralKeys
    .create({
        customer: customerId,
        stripe_version: stripe_version
    })
});

func choosePaymentButtonTapped() {

    guard let uid = Auth.auth().currentUser?.uid else { return }

    var paymentContext: STPPaymentContext?

    let ref = Database.database().reference().child("stripe_customers").child(uid)
    ref.observeSingleEvent(of: .value) { (snapshot) in

        guard let dict = snapshot.value as? [String: Any] else { return }
        guard let customerId = dict["customer_id"] as? String else { return }

        let customerContext = STPCustomerContext(keyProvider: StripeProvider(customerId: customerId))
        paymentContext = STPPaymentContext(customerContext: customerContext)
        paymentContext!.delegate = self
        paymentContext!.hostViewController = self
        paymentContext!.presentPaymentOptionsViewController()
    }
}

class StripeProvider: NSObject, STPCustomerEphemeralKeyProvider {
lazy var functions = Functions.functions()
let customerId: String

init(customerId: String){
    self.customerId = customerId
}

func createCustomerKey(withAPIVersion apiVersion: String, completion: @escaping STPJSONResponseCompletionBlock) {
    let data: [String: Any] = [
        "customerId": customerId,
        "stripe_version": apiVersion
    ]
    functions
        .httpsCallable("createStripeEphemeralKeys")
        .call(data) { result, error in

            if let error = error {
                print(error.localizedDescription)
                completion(nil, error)
            } else if let data = result?.data as? [String: Any] {
                completion(data, nil)
            }
    }
}
}

条带API:

exports.createStripeEphemeralKeys = functions.https.onCall((data, context) => {
const customerId = data.customerId;
const stripe_version = data.stripe_version;
return stripe.ephemeralKeys
    .create({
        customer: customerId,
        stripe_version: stripe_version
    })
});

func choosePaymentButtonTapped() {

    guard let uid = Auth.auth().currentUser?.uid else { return }

    var paymentContext: STPPaymentContext?

    let ref = Database.database().reference().child("stripe_customers").child(uid)
    ref.observeSingleEvent(of: .value) { (snapshot) in

        guard let dict = snapshot.value as? [String: Any] else { return }
        guard let customerId = dict["customer_id"] as? String else { return }

        let customerContext = STPCustomerContext(keyProvider: StripeProvider(customerId: customerId))
        paymentContext = STPPaymentContext(customerContext: customerContext)
        paymentContext!.delegate = self
        paymentContext!.hostViewController = self
        paymentContext!.presentPaymentOptionsViewController()
    }
}

class StripeProvider: NSObject, STPCustomerEphemeralKeyProvider {
lazy var functions = Functions.functions()
let customerId: String

init(customerId: String){
    self.customerId = customerId
}

func createCustomerKey(withAPIVersion apiVersion: String, completion: @escaping STPJSONResponseCompletionBlock) {
    let data: [String: Any] = [
        "customerId": customerId,
        "stripe_version": apiVersion
    ]
    functions
        .httpsCallable("createStripeEphemeralKeys")
        .call(data) { result, error in

            if let error = error {
                print(error.localizedDescription)
                completion(nil, error)
            } else if let data = result?.data as? [String: Any] {
                completion(data, nil)
            }
    }
}
}

我也有同样的问题。问题是我没有在本地运行

onCall

函数。也就是说，虽然我让模拟器在本地运行，但我没有告诉我的客户机使用模拟器。这可以通过调用

useFunctionsEmulator（源：[您的主机]）来完成。

我发现错误

未能加载内部

函数？完整的错误实际上是

错误域=com.firebase.functions code=13“INTERNAL”UserInfo={NSLocalizedDescription=INTERNAL}

这是某种firebase错误，那么：为什么否决？firebase的回复清楚地指出了一个内部错误。您能帮我看一下这个，并告诉我您是否知道可能是什么导致了错误吗？我得到错误
