Authentication function not triggered in emulator behind a proxy #4637
Description
Environment info
firebase-tools: 10.9.2
firebase-functions: 3.21.2
node: 16.14.2
OpenJDK: 11.0.14
Platform: Debian - Bullseye
Test case
Launch the emulator behind a proxy, set a no_proxy env variable, it doesn't matter, authentication calls seem to be sent to the proxy
Steps to reproduce
- set up a proxy server
- set the env vars http_proxy & https_proxy
- set the no_proxy var as "no_proxy=localhost"
- launch the emulator suite behind the proxy (in our case, a self hosted github runner with proxy env set)
- watch your proxy logs
- launch some unit tests to register a new user
- you should see the requests to authentication functions through your proxy
Expected behavior
All requests performed by the emulator should read the no_proxy variable
Actual behavior
Our proxy is restrictive and allows only a few requests, everything seems working but the authentication calls

More context
- tried some proxy configurations
- no_proxy vs NO_PROXY
- no_proxy=localhost vs no_proxy=localhost:8080,localhost:5001,localhost:9099
- tried to downgrade firebase-tools@9.23.3
- less logs, still not working
- tried to upgrade firebase-tools@11.0.1
- works even worse
