I’m using NestJS 10.0.0, with @nestjs/cache-manager=2.2.2 and cache-manager=5.5.2 and cache-manager-redis-yet=5.0.0. However, as the title says, I’m encountering an issue where I can’t make it instantiate inside any service, even though I’ve set global parameter for CacheModule.

Here’s some simple example:

app.module.ts:

import { CacheModule } from "@nestjs/cache-manager";
import { redisStore } from "cache-manager-redis-yet";
import { RedisClientOptions } from "redis";
import { RedisModule } from "./redis.module.ts";

@Module({
  providers: [GenericSeederService],
  imports: [
    CacheModule.register<RedisClientOptions>({
      isGlobal: true,
      store: redisStore,
      url: process.env.REDIS_URL,
    }),
    RedisModule,
  ],
})
export class AppModule {}

redis.module.ts:

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

@Module({
  providers: [RedisService],
  exports: [RedisService],
})
export class RedisModule {}

redis.service.ts:

import { CACHE_MANAGER } from "@nestjs/cache-manager";
import { RedisCache } from "cache-manager-redis-yet";

export class RedisService {
  constructor(
    @Inject(CACHE_MANAGER)
    private readonly cacheManager: RedisCache
  ) {}
 
   private async getKeysFromKeySet(keySet: string): Promise<string[]> {
     const keys: string[] = await this.cacheManager.store.client.sMembers(keySet);
     return keys;
   }
}

And I get this error:

[Nest] 251  - 05/12/2024, 3:38:26 AM   ERROR [ExceptionHandler] Nest can't resolve dependencies of the RedisService (?). Please make sure that the argument Object at index [0] is available in the RedisService context.

I can’t understand why this happens.
