next-i18next: Adding `i18next-ICU` plugin gives an error

Describe the bug

When I add the i18next-ICU plugin it gives an error of

TypeError: Cannot read property 'type' of undefined
at PROJECT_DIRECTORY\node_modules\next-i18next\dist\commonjs\createClient\node.js:64:16

Occurs in next-i18next version

^8.5.0 with i18next-icu -> ^2.0.3

Steps to reproduce

Add the i18next-icu plugin

// next-i18next.config.js

const ICU = require('i18next-icu').default

module.exports = {
    i18n: {
        defaultLocale: 'en',
        locales: ['en', 'de'],
        use: [ICU],
    },
    serializeConfig: false,
}

then do the other steps for handling unserializable configs

Expected behaviour

It should work without giving an error
