NodeJS SDK custom cache store

Hello guys

So, I’m implementing a custom cache store for the nodejs SDK using Redis following this https://github.com/okta/okta-sdk-nodejs#custom-storage

Here the implementation:

import {promisify} from 'util';
const ns = 'my-namespace-user-redis';

export default class RedisCacheStore {
  /**
   * @param {!RedisClient} redisClient
   * @param {!number} keyLimit
   */
  constructor(redisClient, keyLimit) {
    this._store = redisClient;
    this._keyLimit = keyLimit || 100000;
  }

  /**
   * @param {!string} stringKey
   * @return {Object}
   */
  async get(stringKey) {
    const getAsync = promisify(this._store.get).bind(this._store);
    const nskey = `${ns}:${stringKey}`;

    // console.log('retrieveing the key ', nskey);

    const data = await getAsync(nskey);
    // console.log('data from redis', data);
    return data;
  }

  /**
   * @param {!string} stringKey
   * @param {!string} stringValue
   * @return {Object}
   */
  async set(stringKey, stringValue) {
    if (!stringKey) {
      throw new Error('Key is required');
    }
    const nskey = `${ns}:${stringKey}`;
    return this._store.set(nskey, stringValue, 'EX', this._keyLimit);
  }

  /**
   * @param {!string} stringKey
   * @return {Object}
   */
  async delete(stringKey) {
    return this._store.delete(stringKey);
  }
}

But the get method is always receiving the “key” as “undefined”, so, am I doing something wrong?

Thanks
