Firebase 3.2.0 - 创建用户时出现内部错误

Question

我刚刚使用 Firebase 3.2.0 启动了一个新项目（Swift 2.2；iOS 9；Xcode 7.3.1），并且在输入无效电子邮件和弱密码时遇到以下错误作为我授权/注册过程的一部分：

NSError

Error Domain=FIRAuthErrorDomain Code=17999 "An internal error has occurred, print and 
inspect the error details for more information." UserInfo={error_name=ERROR_INTERNAL_ERROR, 
NSUnderlyingError=0x7c0549a0 {Error Domain=FIRAuthInternalErrorDomain Code=3 "(null)" 
UserInfo={FIRAuthErrorUserInfoDeserializedResponseKey=<CFBasicHash 0x7c04bd90 [0x1a701f8]>
{type = immutable dict, count = 3,
entries =>
0 : <CFString 0x7c0fb0c0 [0x1a701f8]>{contents = "errors"} = 
<CFArray 0x7c0713a0 [0x1a701f8]>{type = immutable, count = 1, values = (
0 : <CFBasicHash 0x7c0fac00 [0x1a701f8]>{type = immutable dict, count = 3,
entries =>
0 : <CFString 0x7c051080 [0x1a701f8]>{contents = "reason"} = 
<CFString 0x7c0553f0 [0x1a701f8]>{contents = "invalid"}
1 : <CFString 0x7c055f30 [0x1a701f8]>{contents = "message"} = 
<CFString 0x7c061580 [0x1a701f8]>{contents = "INVALID_EMAIL"}
2 : <CFString 0x7c054fd0 [0x1a701f8]>{contents = "domain"} = 
<CFString 0x7c060290 [0x1a701f8]>{contents = "global"}
}

)}
1 : <CFString 0x7c05aae0 [0x1a701f8]>{contents = "code"} = 
<CFNumber 0x7c073010 [0x1a701f8]>{value = +400, type = kCFNumberSInt64Type}
2 : <CFString 0x7c067e70 [0x1a701f8]>{contents = "message"} = 
<CFString 0x7c0543a0 [0x1a701f8]>{contents = "INVALID_EMAIL"}
}
}}, NSLocalizedDescription=An internal error has occurred, print and inspect the error 
details for more information.}

...我的代码如下....

AuthViewController.swift

if let email = emailField.text where email != "", let password = passwordField.text where 
  password != "" {FIRAuth.auth()?.signInWithEmail(email, password: password) { (user, error) in
    if let error = error {
            if let errorCode = FIRAuthErrorCode(rawValue: error.code) {
                switch errorCode {
                case .ErrorCodeNetworkError:
                    print("A network error occurred")
                case .ErrorCodeUserNotFound:
                    print("ATTEMPTING TO CREATE USER")
                    FIRAuth.auth()?.createUserWithEmail(email, password: password) { (user, error) in
                        if let error = error {
                            if let errCode = FIRAuthErrorCode(rawValue: error.code) {
                                switch errCode {
                                case .ErrorCodeInvalidEmail:
                                    print("invalid email")
                                case .ErrorCodeWeakPassword:
                                    self.insertErrorLabel("Password is considered weak (< 6 characters). Try again")
                                default:
                                    print("Create User Error: \(error)")
                                }
                            }
                        } else {
                            // create a user in the database...
                        }
                    }
                case .ErrorCodeUserTokenExpired:

                ....

执行在 signInWithEmail() 中遇到 .ErrorCodeUserNotFound 情况。然后它在 createUserWithEmail() 中遇到默认情况。

从文档看来，在 createUserWithEmail() 函数中似乎有一个 INVALID_EMAIL 错误键可用，但是，它似乎引发了内部错误，而不是遇到 InvalidEmail 错误情况。

三个问题：

1. 我是否有一个可接受的流程，登录失败导致 createUser？
2. 错误的实际原因是什么？
3. 我该如何解决？

提前致谢。

为了将来参考，我针对上述错误提出了一个错误，Firebase/Google 已确认将在下一版本的 SDK 中解决该问题。
