Firebase 模拟器导出的数据在计算机重新启动时损坏

Question

我通常这样启动模拟器：

firebase emulators:start --import=test/local-dev --export-on-exit=test/local-dev

目的：将之前导出的数据导入到 local-dev 文件夹中，并在模拟器退出时保存所有数据。

重新启动我的开发计算机 (macOS Catalina) 后，我无法再使用 local-dev 文件夹中的数据，因为模拟器无法通过以下控制台输出启动：

firestore: Fatal error occurred:
   Firestore Emulator has exited with code: 1,
   stopping all running emulators 

firestore-debug.log 的内容：

Exception in thread "main" com.google.cloud.datastore.core.exception.DatastoreException: Failed to parse overall export metadata file
        at com.google.cloud.datastore.emulator.impl.ExportImportUtil.parseOverallMetadataFile(ExportImportUtil.java:229)

我注意到firestore_export通常位于 local-dev 中的子文件夹丢失了：

$ ls test/local-dev/
firebase-export-metadata.json

系统关闭过程似乎以某种方式损坏了导出文件夹。有什么想法如何/为什么吗？
