Hello,
When I migrate my app from nuxt 2 to Nuxt 3, it throws multi errors. I actually don't have any idea how to fix this. There's also no suggest on the internet, Nuxt docs page as well.
I hope to receive any advice.

This is my config folder. In nuxt 2 we don't need to create file default.json. But with Nuxt 3, without default.json, will have error Configuration property "env" is not defined.

This is my nuxt.config.ts

This is how I get the config inside component:

My start command is: cross-env NODE_ENV=production nuxt dev.
I set NODE_ENV=production but it alway return the value inside default.json, not value from production.json or dev.json or staging.json.
