flag --export-on-exit fails when script is terminated with CTRL+C

[DerrickAfrifa]

[REQUIRED] Environment info

firebase-tools: 11.4.0

Platform: macOS

[REQUIRED] Test case

run the following command in your terminal: firebase emulators:exec "sleep 20" --ui --only firestore --export-on-exit=./firebase-data once the script enters the sleep phase (you have 20 seconds) hit CTRL+C to kill the script.

[REQUIRED] Steps to reproduce

1. Install firebase-tools globally
2. run firebase emulators:exec "sleep 20" --ui --only firestore --export-on-exit=./firebase-data
3. wait for the sleep command to be triggered
4. hit CTRL+C to kill the emulators

[REQUIRED] Expected behavior

The emulator data should be successfully exported to ./firebase-data

[REQUIRED] Actual behavior

The export fails as the emulator is killed before there is a chance for the export to complete. This is the log:

i  emulators: Received SIGINT (Ctrl-C) for the first time. Starting a clean shutdown.
i  emulators: Please wait for a clean shutdown or send the SIGINT (Ctrl-C) signal again to stop right now.
i  Automatically exporting data using --export-on-exit "./firebase-data" please wait for the export to finish...

Any chance you can upload the logs (*.log) created? As mentioned in the output, the logs contain more information to debug the issue.

Hey @DerrickAfrifa. We need more information to resolve this issue but there hasn't been an update in 7 weekdays. I'm marking the issue as stale and if there are no new updates in the next 3 days I will close it automatically.

If you have more information that will help us get to the bottom of this, just add a comment!

@tonyjhuang The logs seem to indicate issues on the rules runtime. Would you mind taking a look?
