火基协同线onSuccessListener误差

Question

我一直在弄这个：

java.lang.NullPointerException: Parameter specified as non-null is null: method kotlin.jvm.internal.Intrinsics.checkNotNullParameter, parameter it
 at com.bumtzihaus.app.data.AdminRepository.addLogItem_gIAlu_s$lambda-4(Unknown Source:7)
    at com.bumtzihaus.app.data.AdminRepository.$r8$lambda$34A54R8CS3e1Wdzy3o1dgUPicmE(Unknown Source:0)
    at com.bumtzihaus.app.data.AdminRepository$$ExternalSyntheticLambda8.onSuccess(Unknown Source:4)
    at com.google.android.gms.tasks.zzm.run(com.google.android.gms:play-services-tasks@@18.0.0:1)
    at android.os.Handler.handleCallback(Handler.java:883)
    at android.os.Handler.dispatchMessage(Handler.java:100)
    at android.os.Looper.loop(Looper.java:214)
    at android.app.ActivityThread.main(ActivityThread.java:7356)

    at com.android.internal.os.RuntimeInit$MethodAndArgsCaller.run(RuntimeInit.java:492)
    at com.android.internal.os.ZygoteInit.main(ZygoteInit.java:930)

对于特定的防火墙查询，它工作得很好，突然之间，我一直收到这个错误。以下是我所称的：

    ref.set(
        hashMapOf(
            "logCode" to bumtziLog.logCode,
            "timestamp" to FieldValue.serverTimestamp(),
            "itemText" to bumtziLog.items,
            "users" to bumtziLog.users,
            "sessions" to bumtziLog.sessions
        )
    ).addOnSuccessListener {
        result = Result.success(Unit)
    }.addOnFailureListener { exception ->
        result = Result.failure(exception)
        exception.printStackTrace()
        Firebase.crashlytics.recordException(exception)
    }.await()

它似乎在抱怨onSuccessListener的空lambda

Answer 1

这是一个错误的谷歌的部分更新的最新Firebase版本，你应该摆脱这个错误。

Answer 2

我不确定它是否有用，但是尝试为addOnSuccessListener lambda添加类型为addOnSuccessListener的显式可空参数：

ref.set(
    hashMapOf(
        "logCode" to bumtziLog.logCode,
        "timestamp" to FieldValue.serverTimestamp(),
        "itemText" to bumtziLog.items,
        "users" to bumtziLog.users,
        "sessions" to bumtziLog.sessions
    )
).addOnSuccessListener { someResult: Any? ->
    result = Result.success(Unit)
}.addOnFailureListener { exception ->
    result = Result.failure(exception)
    exception.printStackTrace()
    Firebase.crashlytics.recordException(exception)
}.await()

@Sergey答案可以工作，但是如果您不想在每个成功的时候都添加参数。只需将您的防火墙gradle依赖项升级到最新版本即可。在我的情况下，我将com.google.firebase:firebase-bom:29.0.2升级为com.google.firebase:firebase-bom:29.0.3，一切都完成了。
