Hello,

Set your environment mode to lose -

Beyond this recommendation we would not be able to assist further as the issue is with your application config and not the platform.

Best,

I did, it is not working.
It is working in my local environment but not in railway.
I put the env in each package and app.

How railway assign the .env to subfolder?

Nothing to do with Railway, you need to follow turbo's document.

So I can only config the .env in Railway at root?

Railway has nothing to do with .env files, variables are injected directly into the environment and you need to follow turbo's docs to allow it, please read their docs.

Where do the .env place in railway?
at root?

Please see my previous message, Railway does not create .env files.

I'm going to mark this as solved to avoid any further repetition.

Please read turbo's documentation.
