Firebase CLI (Python version) should provide debugging information
Add better debugging information into Firebase CLI (Python) version. The CLI frequently throws the following error but does not provide any further information, even in debug mode.
Failed to call quitquitquit. This often means the server failed to start request to http://127.0.0.1:8081/__/quitquitquit failed, reason: connect ECONNREFUSED 127.0.0.1:8081 {"message":"request to http://127.0.0.1:8081/__/quitquitquit failed, reason: connect ECONNREFUSED 127.0.0.1:8081","type":"system","errno":"ECONNREFUSED","code":"ECONNREFUSED"}
or
Error: User code failed to load. Cannot determine backend specification
Details of the error can however be found in the GCP Console and Cloud Build. The same error messages should appear in the CLI as the Console is not a scalable way to maintain/deploy to production.
