I create this file for cache:

const cache: any = {}; // eslint-disable-line @typescript-eslint/no-explicit-any

export const customCache: {
  getDataFromCache(key: string): {};
  setDataInCache(key: string, value: {}): void;
} = {
  getDataFromCache: function(key: string) {
    return cache[key];
  },

  setDataInCache: function(key: string, value: {}) {
    cache[key] = value;
  },
};

Then in a new file I create special object, where I use customCache.getDataFromCache and customCache.setDataInCache, then I use this object in two api routes. But these routes access different instances of the customCache object. What could be the problem?
