NUXT0053Use runtimeConfig instead of process.env in app code
Flags plain env in app code in Nuxt runtime code before it leaks into runtime behavior.
vite-doctor/nuxtruntime-configerrorSuggestion
Why it happens
Runtime configuration has different server and client visibility. Using the framework API keeps environment data typed and scoped.
Fix
Read configuration through useRuntimeConfig() instead of process.env in app code.
Example
Use runtime config in app code
Before
const apiBase = process.env.NUXT_PUBLIC_API_BASE
After
const apiBase = useRuntimeConfig().public.apiBase
