我试图构建一个firebase登录函数，但是即使抛出的异常被捕获，代码也会崩溃。
当我将异常作为日志输出时，代码可以正常工作，但是当我将其作为异常传递时，代码会崩溃。
我想将异常传递给MainActivity，以便在那里正确处理它，即将exception.message输出为吐司。
登录过程使用有效的登录数据，只有在firebase报告异常时才会崩溃。

internal var loginResult = MutableLiveData<LoginResult>()

x

inner class LoginResult {
        var authResult: AuthResult? = null
        var exception: Exception? = null
        var isSuccessful = false

        constructor(authResult: AuthResult?, isSuccessful: Boolean) {
            this.authResult = authResult
            this.isSuccessful = isSuccessful
        }
        
        constructor(authResult: AuthResult?, exception: Exception?, isSuccessful: Boolean) {
            this.authResult = authResult
            this.exception = exception
            this.isSuccessful = isSuccessful
        }
    }

fun login(context: Context, email: String, password: String) {
        FirebaseAuth.getInstance().signInWithEmailAndPassword(email, password)
            .addOnCompleteListener { task ->
                if (task.isSuccessful) {
                    loginResult.value = LoginResult(task.result, task.isSuccessful)
                    startSession(context, LoginType.CREDENTIAL)
                    saveCredentialsEncrypted(context, email, password)
                } else {
                    try {
                        loginResult.value = LoginResult(task.result, task.exception, task.isSuccessful)
                    } catch (e: FirebaseAuthInvalidCredentialsException) {
                        loginResult.value = LoginResult(task.result, e, task.isSuccessful)
                    } catch (e: Exception) {
                        loginResult.value = LoginResult(task.result, e, task.isSuccessful)
                    }

                }
            }
    }

的数据
UPDATE：抛出错误是因为我试图访问task.result时没有结果，请参阅try catch块。
要修复此错误，我将null作为authResult传递

fun login(context: Context, email: String, password: String) {
        FirebaseAuth.getInstance().signInWithEmailAndPassword(email, password)
            .addOnCompleteListener { task ->
                if (task.isSuccessful) {
                    loginResult.value = LoginResult(task.result, task.isSuccessful)
                    startSession(context, LoginType.CREDENTIAL)
                    saveCredentialsEncrypted(context, email, password)
                } else {
                    loginResult.value = LoginResult(null, task.exception, task.isSuccessful)
                }
            }
    }
