Env variable for cors

[Falci]

I'd like to define CORS origin via env vars.

I tried:

serve:
    cors:
        origin: '{env.CORS_ORIGIN}'

But it seems to return the raw string:

The 'Access-Control-Allow-Origin' header contains the invalid value '{env.CORS_ORIGIN}'.

What's the proper way to make it dynamic ?

${CORS_ORIGIN} Does this work for you?

Thanks. This works:

serve:
    cors:
        origin: '${CORS_ORIGIN}'

It seems like quotes are required.

My original approach was based on this other config.
TBH, it's a bit confusing: in the same config file there are different ways to read env vars.

We don't support dynamic env variables like we do in those examples. ${ENV_VAR} is the YAML syntax that interpolates values while reading it. So it won't be dynamic and written statically once you build artifacts.
