I have been getting this error When I try to start my firebase emulator, so far I have tried the followings:

1. tried reinstalled node and using lower versions as far as they go all the way to v12
   2)Java sdk reinstallation
   3)firebase cli tools reinstallation

but the error persists.

i pubsub: Pub/Sub Emulator logging to pubsub-debug.log
! pubsub: Fatal error occurred:
Pub/Sub Emulator has exited with code: 1,
stopping all running emulators
i pubsub: Stopping Pub/Sub Emulator
i hub: Stopping emulator hub

this is the error log output.
