Hello, thanks for reaching out. I see that you added the node options to almost all scripts. You only need to add them to the scripts that are running your build output:

"preview": "NODE_OPTIONS='--import ./public/instrument.server.mjs' nuxt preview",
"start": "NITRO_PORT=4000 NITRO_HOST=0.0.0.0 node  --import .output/public/instrument.server.mjs .output/server/index.mjs"

In general, we optimize for the production build of applications. And thanks for filing the issue, I will make this more clear in the docs :)

Makes sense! Sorry for that @s1gr1d !

You're welcome! However, I fixed this and you should be able to add the --import flag in dev mode with v8.26.0

Hi! I know this is a closed issue but I'm facing this issue in an Astro project while trying to upgrade to >=8.0. I can't manage to make a reproduction atm so I'm trying to find clues about what could be causing this, and be able to report it properly. Do you know why this error occurs at all?
