Functions emulator not working after upgrade to 10.2.2 when using Yarn PnP

[ericvera]

[REQUIRED] Environment info

firebase-tools: 10.2.2

Platform: macOS

[REQUIRED] Test case

• The repro below works perfectly with 10.1.5.
• In the case of 10.2.2 it only works if I run the command outside or the package.json script (directly on console).
• Running a package.json script that does not include the functions emulator (only auth and Firestore) still works.
• My guess is that something changed between 10.1.5 and 10.2.2 that is trying to load the node project in process or something similar that now goes through Yarn. Some logging on what the error is would be helpful to troubleshoot.

[REQUIRED] Steps to reproduce

1. Create a project that uses yarn pnp
2. Add a script to package.json such as
   "emulate": "firebase --project=test-project emulators:start --only auth,functions,firestore --import .firebase-emulator --export-on-exit",
3. Run the script yarn emulate

[REQUIRED] Expected behavior

Emulator runs

[REQUIRED] Actual behavior

Emulator fails showing the following in the console:

@ericvera Thank you for detailed report!

I also don't have immediate bunch on what might be going wrong. I'm going to try to push out a change to make error messages more useful to help us debug the issue. In the meantime, can you help us by sharing a small sample that can reproduce the issue? I've never used that setup, and while we don't officially support yarn pnp, it seems like it's always worked before.

Hey @ericvera. 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!
