App Engine nodejs with automatic scaling not going to zero instances with no traffic

I'm trying to deploy an app engine on google cloud with the following app.yaml :

runtime: nodejs
env: flex
entrypoint: node app.js
automatic_scaling:
  min_instances: 0
  min_idle_instances: 0
  cool_down_period_sec: 180

I would expect active instances to go down to 0 when there is no traffic (I accept initial warmup latency) Obviously i keep seeing at least 2 active instances running. What am i missing, thank you !

I implemented warmup routes (doing nothing) with no impact

Thank you, the documentation has multiple URLs concerning app engine not always saying the same thing.

i changed my app.yaml like this and it looks like it's working as expected now

runtime: nodejs18

entrypoint: node app.js
automatic_scaling:
  min_instances: 0
  min_idle_instances: 0

You're using Flex. Flex can't go down to 0 instances i.e. it can't scale to zero (see documentation)
