Environment variables mislabeled as "cannot be overridden"

[ZackKnopp]

Forgive me if this is the wrong place to raise this issue.

Documentation here states that the environment variable "NODE_ENV" cannot be overridden in google app engine standard environment for Node. However, the following yaml file successfully overrides the variable.

runtime: nodejs8
env_variables:
    NODE_ENV: development

Am I missing something?

👋 @ZackKnopp . Thanks for reporting the issue, looks like the docs are wrong, as NODE_ENV can be changed. I get this changed internally.
