I follow these steps to achieve import Firestore data from the windows machine on mac.

1. run firebase emulators:start --import=./mydir --export-on-exit
2. on firebastore emulator ui create a doc
3. stop emulator
4. copy all_namespaces_all_kinds.export_metadata and output-0 from your previous dir to mydir
5. run firebase emulators:start --import=./mydir --export-on-exit and now you have imported the data 😃

Hey! I just wanted to say that this issue is still happening between Ubuntu (importing) and Windows (exporting). I’m not opening another issue as it was said in this one 2433 to consolidate here, but I’ll leave info to help with the reproduction of it:

[REQUIRED] Environment info

[REQUIRED] Steps to reproduce

[REQUIRED] Expected behaviour

Should be able to run with all the imports.

[REQUIRED] Actual behaviour
