Setting lambda env variables does not work.

[horenmar]

I am testing zappa for deployment of event-driven lambda functions (no APIGW component) and ran into trouble with env variables. According to documentation, zappa_settings.json like this

 {
    "dev": {
    ...
    "environment_variables": {"NICE": "To", "SEE" : "You"},
    ...
    }
}

should set two environment variables for the lambda, NICE and SEE. However, the lambda does not have these environment variables set, as verified by both print(os.environ) and looking at the lambda in AWS management console. Adding an environment variable manually works.

I don't know what you mean by "Lambda does not have these environment variables set."

Zappa environment variables have existed long before "Lambda environment variables", which I think were only added last week. They're not the same thing, and I don't know how the two interact. Can somebody confirm this? Maybe your AWS environment variables are overriding the Zappa ones, but I don't see how that's possible. I think this more likely due to there being no APIGW than AWS Env, but needs investigation.

I expected the environment_variables to be set as Lambda environment variables.

You mean the AWS ones?

[Miserlou]

If we do add support for those, it'll likely be done in a vendor prefixed way, ex aws_environment_variables

Cannot confirm yet, still investigating.

Confirmed it works with and without API Gateway, feel free to ask me to reopen if you can provide steps to reproduce.
