auto import failing when using my module deployed on npm

[fusionbeam]

Hi,

I've created a custom module that has a few composeables.
When I use the module installed via npmjs I get errors of undefined on pretty much all nuxt utilities (useRuntimeConfig, defineNuxtPlugin etc).
When I use the module locally with link it works fine.

Doesn't seem to be a build/package problem; I get no errors if I use explicit imports in the module composeables

Using:

• node v22.19.0
• nuxt 4.1 (same happens on 3.17)
• pnpm (same problem with yarn)

Any idea why this might happen, how to troubleshoot ? I'll gladly submit a fix, just somewhat new to nuxt modules and need a bit of guidance on where to start ...

Thank you,
Rares
