Fail to create an MMKV instance [XXX] in NAPI.

在HarmonyOS Next系统创建MMKV，偶现会报出如下错误：

Error name:Error
Error message:Fail to create an MMKV instance [XXX] in NAPI.
Stacktrace:
Cannot get SourceMap info, dump raw stack:
at mmkvWithID (xxx|@tencent/mmkv|2.0.1|src/main/ets/utils/MMKV.ts:61:1)
....

创建代码如下：
private mmkv: MMKV
constructor(context: Context, fileName: string) {
this.mmkv = MMKV.mmkvWithID(fileName, MMKV.MULTI_PROCESS_MODE, undefined, context.filesDir + "/mmkv")
}

观察线上崩溃数据，崩溃次数和崩溃设备数大致相等，也就是绝大部分设备只会崩溃一次。崩溃日志也仅能看到上面这些。请问该崩溃产生的可能的原因是什么？

No idea.

You should provide logs from MMKV.

I can only see these logs. How to get more logs from MMKV？

Redirect MMKV's log to your log collect framework.
Demo:
https://github.com/Tencent/MMKV/blob/master/OpenHarmony/entry/src/main/ets/Util/MyMMKVHandler.ets

I just see the "rootPath" param is "The folder of the MMKV instance, defaults to $(FilesDir)/mmkv"，does it mean the param (context.filesDir + "/mmkv") is duplicate for this case？

It's redundant. Follow our official wiki for guidance. https://github.com/Tencent/MMKV/wiki/ohos_setup#setup

Got it. I will use MMKVHandler to export logs. Thanks
