本番環境で奇妙なエラーが多数発生していますが、これは少数のユーザーにのみ発生するため、99% のユーザーは問題ありません。

これが TranslationWorkerFactory のコードです。私はダガーアシスト注入を使用して、ワーカークラスに依存関係を注入しています。

class TranslationWorkerFactory @Inject constructor(
    private val workerFactories: Map<Class<out ListenableWorker>, @JvmSuppressWildcards Provider<ITranslationWorkerFactory>>
) : WorkerFactory() {
    override fun createWorker(
        appContext: Context,
        workerClassName: String,
        workerParameters: WorkerParameters
    ): ListenableWorker? {
        val foundEntry =
                workerFactories.entries.find { Class.forName(workerClassName).isAssignableFrom(it.key) }
        val factoryProvider = foundEntry?.value
                ?: throw IllegalArgumentException("unknown worker class _name: $workerClassName")
        return factoryProvider.get().create(appContext, workerParameters)
    }
}

なぜこれが起こるのか分かりません。ワーカーが行うことは、大きなjsonをダウンロードして解析することなので、例外をスローする理由になる可能性がありますが、それが関連している可能性があるかどうかは私の推測です.

これが発生する理由を知っている人はいますか？

ありがとう
