Can not import data to the emulator

[pascalbe-dev]

When running an import for the local emulator, the data is not really imported to the firestore emulator.

Steps to reproduce the behavior

• start the firebase emulator with a demo project ID (firebase emulators:start --project demo-my-project --config some-folder/firebase.json) (a firebase.json which includes the activated firestore emulator on port 8080 is present in "some-folder")
• setting the FIRESTORE_EMULATOR_HOST environment variable to localhost:8080
• running a import command, e.g.: firestore-import -y -b users.json -n users

Expected behavior

• the data gets imported into the database (this is how it works with actual firebase projects)

Actual behavior

• I get an error message about a missing GOOGLE_APPLICATION_CREDENTIALS variable

• when I now point this env variable to the service account key for a different environment, the import command works (success message), but data is still not imported in the emulator.

Final thoughts

So, basically, I see two problems:

• why is the service account key required for the emulator?
• why is the data not imported even with a service account key?

Forked here https://github.com/cuong0993/node-firestore-import-export

Pass GOOGLE_CLOUD_PROJECT and FIRESTORE_EMULATOR_HOST to connect with emulator. For example,

GOOGLE_CLOUD_PROJECT=demo- FIRESTORE_EMULATOR_HOST=localhost:8089 firestore-import --backupFile db.json --yes

@cuong0993 I just tried this and it worked like a charm. Thank you for this!
