astro-i18next type error on local builds

[clee231]

I'm trying to build this project locally, however visiting the local dev server after running yarn start:build returns an error regarding the language selector.

23:59:13 [200] /en/ 83ms
23:59:13 [ERROR] Cannot read properties of undefined (reading 'map')

I've tried building this project using Node 20 and 21, but both return the same error.

It seems to be referring to this https://github.com/yassinedoghri/astro-i18next/blob/v1.0.0-beta.21/src/components/LanguageSelector.astro#L26, where i18next.languages seems to be not defined. Is there a configuration file that needs to be updated?
