  page: '/'
}

and i found no solution yet.

i18n.config.js

const path = require("path");

module.exports = {
    i18n: {
        locales: ["en", "fr", "pt"],
        defaultLocale: "pt"
    }
};

next.config.js

require("dotenv").config();
const { i18n } = require("./i18n.config");

module.exports = {
    env: {
        API_BASE_URL: process.env.API_BASE_URL,
        SiteKey: process.env.SiteKey,
        SecretKey: process.env.SecretKey
    },
    i18n
};

I'm using serverSideTranslations on almost every page except some componentsand pages.[id].

ex. on index.js

import { serverSideTranslations } from "next-i18next/serverSideTranslations";
import { useTranslation } from "next-i18next";

const Home = ({ expe }) => {
    //const islang = i18n.isInitialized;
    const { t } = useTranslation("common");
...
...
...
export const getStaticProps = async ({ locale }) => {
    //const obj = { namespacesRequired: ["common", "footer", "navbar"] };
    const res = await getExperiencias(2); //limite = 2
    const exp = await res.json();

    return {
        props: {
            ...(await serverSideTranslations(locale, [
                "common",
                "footer",
                "navbar"
            ])),
            expe: exp
        } // will be passed to the page component as props
    };
};

export default Home;
