Double language in url after changing language and click on a link for a redirect

[yertech]

Hello,

I just started a project, followed some tutorials to install gatsby-plugin-react-i18next. But I have an issue and I don't know if I can resolve that.

Scenario :
This is a sample project : GatsbyErrorI18n

• Default language is EN

• I have a link on the home page and when I click it I m redirected to the /localhost:8000/destinations/test.
  Where "test" is a slug :
  

• Now I come back to the homepage

• I change the language to "FR"

• The path is now /localhost:8000/fr, all good

• I click on the link (url on the link : http://localhost:8000/fr/destinations/test/), and I have /localhost:8000/fr/fr/destinations/test => so double fr

Index page:

import { graphql } from "gatsby";
import { Link, useTranslation } from "gatsby-plugin-react-i18next";
import * as React from "react";
import LanguageSwitcher from "../components/languageSwitcher";

const IndexPage = () => {
  const { t } = useTranslation();
  return (
    <section className="relative table w-full pt-16 md:pt-44 pb-56" id="home">
      <div className="container relative">
        <LanguageSwitcher />
        <div className="grid grid-cols-1 items-center my-8 gap-[30px]">
          <div>
            <h4 className="font-bold lg:leading-normal leading-normal text-4xl lg:text-6xl mb-6 mt-5">{t("title")}</h4>
          </div>
          <Link
            to={"/destinations/test"}
            className="text-lg font-medium text-black hover:text-red-500 duration-500 ease-in-out rounded-md border border-gray-300 w-40"
            placeholder={""}
          >
            {"Click here"}
          </Link>
        </div>
      </div>
    </section>
  );
};

export default IndexPage;

export const query = graphql`
  query ($language: String!) {
    locales: allLocale(filter: { ns: { in: ["common", "index"] }, language: { eq: $language } }) {
      edges {
        node {
          ns
          data
          language
        }
      }
    }
  }
`;

Plugin config :

{
      resolve: "gatsby-plugin-react-i18next",
      options: {
        languages,
        defaultLanguage,
        siteUrl: "https://www.yoursite.com/",
        i18nextOptions: {
          fallbackLng: defaultLanguage,
          supportedLngs: languages,
          defaultNS: "common",
          interpolation: {
            escapeValue: false, // not needed for react as it escapes by default
          },
        },
      },
    },
