Set environment variable in config as code with 
railway.toml

I'm finding it harder than expected to work out how to set an environment variable in the config from the docs - I tried [env] and [build.env] as the railway.toml section titles

I am trying to set the NIXPACKS_POETRY_VERSION = "2.1.2" so that my poetry installation will not error out (its default version is sufficiently old that it doesn't recognise the pyproject.toml config as valid)

I figured this would be trivial but there are docs on env vars and docs on config as code, and neither seem to refer to the other

edit - I read the docs and am getting the impression it's actually not possible despite the examples I saw on GitHub, and that I should probably use a nixpacks.toml file

To answer my own question (well, not quite, I don't know about railway.toml) - in nixpacks.toml you can set them with [variables]`

Hello,

Yep this functionality is limited to nixpacks.toml files, we don't let you set variables in a railway.json file since setting variables in CaC is generally poor practice, but makes more sense to set them in config files for builders.

Best,
Brody
