Running vanilla extract on the server

[atabel]

Hi, I haven't found any reference in docs about running vanilla extract on the server (apart from Next).
I've tried to setup a simple node (express) server that outputs an html generated with ReactDomServer.renderToString but I get this error from vanilla extract:

Error: Styles were unable to be assigned to a file. This is generally caused by one of the following:
    
    - You may have created styles outside of a '.css.ts' context
    - You may have incorrect configuration. See https://vanilla-extract.style/documentation/getting-started

Do I need to compile my server code with any bundler before running it? I'm just running it with ts-node

Thanks in advance for the help ;)

No idea, but there's some issues with the same error, and maybe you can check that a regular .css file works?
