我一直在得到這個：
java.lang.NullPointerException: Parameter specified as non-null is null: method kotlin.jvm.internal.Intrinsics.checkNotNullParameter, parameter it

對于某些 Firestore 查詢；它運行良好，突然間我不斷收到此錯誤。這是我想要呼叫的：
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
uj5u.com熱心網友回復：
我不確定它是否有幫助，但嘗試Any?為addOnSuccessListenerlambda添加顯式可為空的引數：
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()
