addPath seems not working

🐛 Bug Report

It seem that addPath not working, neither with ChainedBackend, neither stand alone, neither yaml, neither json, I have tried every possible options. The file with missing keys not created. No exception is thrown. Please advice.

To Reproduce

import i18n from 'i18next'
import FsBackend from 'i18next-fs-backend'
import ChainedBackend, {ChainedBackendOptions} from "i18next-chained-backend";

const i18nextOptions = {
    debug: true,
    initImmediate: false,
    fallbackLng: 'en',
    lng: 'en',
    preload: ["en", "de"],
    ns: 'translation',
    defaultNS: 'translation',
    backend: {
        backends: [
            FsBackend,
        ],
        backendOptions: [{
            loadPath: './src/i18n/locales/{{lng}}/{{ns}}.yaml',
            addPath: './src/i18n/locales/{{lng}}/{{ns}}.missing.json',
            // expirationTime: 7 * 24 * 60 * 60 * 1000, // 7 days
        }]
    }
}


i18n
    .use(ChainedBackend)
    .init<ChainedBackendOptions>(i18nextOptions)


await i18n.changeLanguage("en")
console.log(i18n.t('home.title', {
    lng: "de"
}))

console.log(i18n.t('home.missing'))

Expected behavior

File translation.missing.yaml will be created with home.missing key
