Failed to load static props with empty paths and fallback - next.js

Question

I have the following code on my Dynamic Routing page [id] that I am trying to use with next-i18next translations. However, it is throwing an error when being deployed on Vercel (working locally). I am trying to use the fallback function with an empty path array to somehow accept all possible paths(?). In my console I am getting a statuscode 500 GET-error and a "Failed to load static props"-error.
It is working when I specify a specific id within getStaticPaths and go to that matching path. However, I can't possibly specify thousands of ids for this to work. Shouldn't the fallback take care of this or how can I get past this?
export async function getStaticPaths() {
return {
paths: [], fallback: true
}
}
export async function getStaticProps(context) {
return {
props: {
params: context.params,
...(await serverSideTranslations(context.locale, ["common"])),
},
}
}
Update:
This is the Vercel function log (xxxxx-values is some id's I removed)

This line was missing in my next-i18next-config
localePath: path.resolve('./public/locales'),
