- you need put the env in front of the command rather than using export, it seems quaser build need in the command session (when case you cannot use .env)
- it is a replacement of text rather than run in js, so you may check the generated code to see is the actual value you want
- use args in docker-compose to pass the variable instead of ENV, it may make you life easier. Seems the process.env is not traditional env. But it similar like a argument passing
