Getting "createContext only works in Client Components" while using createIntl

I'm using NextJS 13 with the app router. In a server action I'm trying to obtain localized text. For this I've created the following function:

import { createIntl, createIntlCache, IntlShape } from "react-intl";
import { SupportedLocale } from "@/types/locale";

const cache = createIntlCache();

export const getIntlForBackend = (locale: SupportedLocale): IntlShape => {
  return createIntl(
    {
      locale,
      defaultLocale: SupportedLocale.SPANISH,
      messages: {},
    },
    cache
  );
};

My understanding is that createIntl is made for these types of scenarios (backend code in which React context is not available.

From https://formatjs.io/docs/react-intl/api): createIntl: In a non-React environment (Node, vue, angular, testing... you name it), you can directly create a intl object by calling this function with the same configuration as the IntlProvider.

Despite this I'm getting the following error:

Unhandled Runtime Error Error: createContext only works in Client Components. Add the "use client" directive at the top of the file to use it. Read more: https://nextjs.org/docs/messages/context-in-server-component

I've traced the calls from the start of the server action until this function is called, and I'm sure it's this that is causing it.

For example I can replace

const intl = getIntlForBackend(locale);

with

const intl = {
  formatMessage: (a: any, b: any) => "testing",
};

and no longer get the error and the code in the server action completes successfully.

Any tips on what could be happening? Ty!

The issue here was that you shouldn't import from react-intl but from @formatjs/intl:

import { createIntl, createIntlCache, IntlShape } from "@formatjs/intl";
