App Engine Node flexible instance constantly running

I have several Firebase-Queue NodeJS instances running in my project on App Engine.

The instances seems to be constantly running, producing errors after trying a GET request.

13:33:36.078
{"method":"GET","latencySeconds":"0.000","referer":"-","host":"-","user":"-","code":"502","remote":"130.211.0.96","agent":"GoogleHC/1.0","path":"/_ah/health","size":"166"}

[error] 32#0: *80631 connect() failed (111: Connection refused) while connecting to upstream, client: 130.211.1.11, server: , request: "GET /_ah/health HTTP/1.1", upstream: "http://172.18.0.2:8080/_ah/health", host: "10.128.0.5"

My App.yaml file when i deploy my Node apps looks like this:

runtime: nodejs
env: flex
service: album-queue
skip_files:
- ^(node_modules)

handlers:
- url: .*
  script: build/index.js

I think it must have something to do with all these these GET requests it's trying to do internally, but I don't know how to stop them / fix it. My bills are raking up fairly quickly, so would be pretty nice to get it fixed >_<

App Engine Flex doesn't scale to zero like the standard environment does. There will always be at least one instance running (default is actually 2). The requests you see are the normal health checks.
