⚠  Your function was killed because it raised an unhandled error.

Were you able to successfully deploy your functions?

Getting this error on deploy: package.json in functions directory has an engines field which is unsupported. Valid choices are: {"node": "8"}, {"node": "10"}, and {"node":"12"}.

I found a few problems with this issue:

• I couldn't figure out how to label this issue, so I've labeled it for a human to triage. Hang tight.
• This issue does not seem to follow the issue template. Make sure you provide all the required information.

Turns out I had two versions of the Firebase CLI installed on my Mac. A very old version installed in "/usr/local/bin/firebase", and the newest version in "/Users/username/.nvm/versions/node/v18.15.0/bin/firebase" When using the "Firebase" command to deploy or run emulators, it was using the old version of the CLI, pre Gen 2. I deleted that one and now 'Firebase' commands are using the updated CLI.

Closing for above reason.
