next-translate-routes: "No translate routes data found. next-translate-routes plugin is probably missing from next.config.js"

I keep getting this error although I followed all the basic steps. I can even see the debug log in the terminal with all the redirects and rewrites created by the plugin, but somehow I’m still getting this error.

What I did:

1. Wrap you next config with the next-translate-routes plugin

// next.config.js
const { i18n } = require("./next-i18next.config");
const withTranslateRoutes = require("next-translate-routes/plugin")

module.exports = withTranslateRoutes({
  pageExtensions: ["page.tsx", "page.ts", "page.jsx", "page.js"],
  reactStrictMode: true,
  eslint: {
    ignoreDuringBuilds: true,
  },
  esModule: true,
  images: {
    domains: [
      //...
    ],
  },
  i18n,
  translateRoutes: {
    debug: true,
  },
});

1. Define your routes

// _routes.json
{
  "/": {
    "en": "hi",
    "es": "hola",
    "pt-BR": "oi"
  }
}

1. Wrap you _app component with the withTranslateRoutes hoc

import { appWithTranslation } from "next-i18next";
import { wrapper } from "../redux";
import { withTranslateRoutes } from "next-translate-routes";

function MyApp({ Component, pageProps }: AppProps) {
  /**/
  return (
    <>
      <Component {...pageProps} />
    </>
  );
}

export default withTranslateRoutes(
  appWithTranslation(wrapper.withRedux(MyApp))
);

What I get in terminal:

[next-translate-routes] - Redirects: [
  {
    source: '/pt-BR/(hi|hola)/downloads/',
    destination: '/oi/downloads/',
    locale: false,
    permanent: false
  },
  {
    source: '/en/(oi|hola)/downloads/',
    destination: '/en/hi/downloads/',
    locale: false,
    permanent: false
  },
...
]
[next-translate-routes] - Rewrites: [
  {
    source: '/(oi|hi|hola)/downloads/',
    destination: '/downloads/'
  },
  {
    source: '/(oi|hi|hola)/about/',
    destination: '/about/'
  },
...
]

And eventually:

Error: [next-translate-routes] - No translate routes data found. next-translate-routes plugin is probably 
missing from next.config.js

I have searched for other issues here and in Google, but haven’t find anything similar. What am I missing?
