i have chrome extension written in react with react-i18next used for translations when for the resuable component i think 4 level nesting is throwing error

Type instantiation is excessively deep and possibly infinite.

PasswordForm component: 
 const { t } = useTranslation("translation", {
    keyPrefix: i18nKeyPrefix,
  });


<TextField
          autoFocus={autoFocus}
          id="password"
          label={t("choose_password.label")}
 		 .....  
        />

reusable component PasswordForm called through some other component

<PasswordForm
              i18nKeyPrefix="welcome.set_password"
              formData={formData}
              setFormData={setFormData}
            />

so the final translation is welcome.set_password.choose_password.label

config::

import { defaultNS, resources } from "./i18n/i18nConfig";

declare module "i18next" {
  interface CustomTypeOptions {
    defaultNS: typeof defaultNS;
    resources: (typeof resources)["en"];
  }
}

what is the different between declare module "react-i18next" and declare module "i18next" i see error resolved when i use react-i18next

[adrai]

declare module "react-i18next" is for the old version...
You probably don't see errors with that because there is also no type safety

I just had a very strange case.

I had the i18next.d.ts in the /src/@types/ directory and was struggling with the TS2589 error. After I moved the file to src/ it suddenly worked.
