Currently GCP Cloud functions only support Node 8. Node8 is out of support since end of 2019. Node10 runtime of GCP functions is in beta phase since April 2019.
Google does not commit to any SLAs on a beta runtime.
As other GCP services and libs require at least Node10, there is basically no way to use GCP functions together with other GCP services in a production setup.
Is there any communication from GCP how and when to solve this?
It seems like GCP is now officially supporting Node10. The documentation https://cloud.google.com/functions/docs/concepts/nodejs-10-runtime. Node 8 will be deprecated on 2020-06-05.
I'm very unhappy about the bad communication of these changes from GCP. I've heard about the Node10 GA via Firebase newsletter and the very short upgrade window.
A colleague of mine and I investigated this, we work in GCP Support, and there is no communication about this nowadays. If you want, you can create a Feature Request here to ask for this information.
