Firebase Function deploy failed on loading user code due to Node12

[Huncuska]

Hi,

After creating an Nx workspace, and using Create Firebase Application to link with my existing firebase app, I encountered a few errors.

First I fixed with the patch in #https://github.com/simondotm/nx-firebase/issues/44 But then on my function deploys I had the following error:

Function failed on loading user code. This is likely due to a bug in the user code. Error message: Error: please examine your function logs to see the error cause: https://cloud.google.com/functions/docs/monitoring/logging#viewing_logs. Additional troubleshooting documentation can be found at https://cloud.google.com/functions/docs/troubleshooting#logging. Please visit https://cloud.google.com/functions/docs/troubleshooting for in-depth troubleshooting documentation.

GCP journal logs:

The logs were not very descriptive but I figured out it was probably due to the node12 engine not being supported anymore ny latest versions.

The fix was to replace the engine version in my generated package.json

  "engines": {
    "node": "12"
  },

  "engines": {
    "node": "16"
  },

As Nx now generates workspaces with node 16^, I figured the generation script at @simondotm\nx-firebase\src\generators\application\files\package.json__template__ could also use a newer version

PS: great work thanks for the pluggin!

Thanks @Huncuska , a new version of the plugin with node 16 support is coming soon.

I've added some documentation about Firebase & Node versions which might be helpful.
