Hi all, I'm trying to use an env var in a BUILD file, specifically for the

runtime

field in a

python_awslambda target

. If I do this:

python_awslambda(
    name="configuration_change",
    runtime=env("LAMBDA_PYTHON_VERSION"),
    handler="configuration_service.py:configuration_change_handler",
)

I get the error:

The python_awslambda target [/snip]configuration_change must specify either a runtime or complete_platforms or both.

Is this possible?

That suggests to me that the LAMBDA_PYTHON_VERSION environment variable isn't being propagated into the BUILD file properly, and thus that is ending up as something like

runtime=None

. Can you confirm you're running with that env var set as you'd expect?

Ahh yes, I am a goose, the env var simply wasn't set 🤦‍♀️ Thank you kindly
