`this.cacheManager.store.client` is undefined about cache-manager

You should use the @nestjs/cache-manager, follow the caching doc, and replace cache-manager-redis-store with cache-manager-redis-yet

Module

// redis.module.ts
import { CacheModule } from '@nestjs/cache-manager';
import { Module } from '@nestjs/common';

// import * as redisStore from 'cache-manager-redis-store'; replace the redisStore
import { redisStore } from 'cache-manager-redis-yet'; // 

import { RedisService } from './redis.service';

@Module({
  imports: [
     CacheModule.register({
      isGlobal: true,
      store: redisStore,
      url: `redis://${process.env.REDIS_HOST}:${process.env.REDIS_PORT}`,
    }),
  ],
  providers: [RedisService],
  exports: [RedisService],
})
export class RedisModule {}

Service

// redis.service.ts
import { CACHE_MANAGER } from '@nestjs/cache-manager';
import { Inject } from '@nestjs/common';

import { Cache } from 'cache-manager';
import { RedisStore } from 'cache-manager-redis-yet';
import { RedisClientType } from 'redis';

export class RedisService {
  client: RedisClientType;
  constructor(
    @Inject(CACHE_MANAGER)
    private readonly cacheManager: Cache,
  ) {
    this.client = (this.cacheManager.store as RedisStore).client as RedisClientType;
  }

  async getKeysFromKeySet(keySet: string): Promise<string[]> {
    const keys: string[] = await this.client.sMembers(keySet);
    return keys;
  }
}

Yeah, this turned out to be the bogus issue in the end and it was some other problem which I managed to solve. My apologies, I totally forgot that I made this issue.
