Caching mechanism is not storing data in Redis

Hello,
I am quite desperate right now and I am looking for any kind of help.
I am trying to setup cache mechanism in my project using GraphQL and Redis.
This is how I configure GraphQLModule:

GraphQLModule.forRoot({
                cache: new BaseRedisCache({
                    client: new Redis({
                        host: 'localhost',
                        port: 6379,
                        password: 'Zaq1xsw@',
                    }),
                    cacheControl: {
                        defaultMaxAge: 10000
                    },
                }),
                plugins: [
                    responseCachePlugin()
                ],
                autoSchemaFile: path.resolve(__dirname, `../generated/schema.graphql`),

                installSubscriptionHandlers: true,
            }),

This is how I’ve created queries and mutations:

@Resolver()
export class AuthResolver {
    constructor(
        private readonly prismaService: PrismaService,
        private readonly authService: AuthService,
    ){}

    @Query(returns => String)
    async testowe(@Args(`input`) input: String, @Info() info: any) {
        info.cacheControl.setCacheHint({ maxAge: 5000, scope: 'PUBLIC' });
        return 'test';
    }
}

When I am using GraphQL Playground and try this query I get the response and header looks like that:

HTTP/1.1 200 OK
X-Powered-By: Express
Access-Control-Allow-Origin: *
Content-Type: application/json; charset=utf-8
cache-control: max-age=5000, public
Content-Length: 28
ETag: W/"1c-2Df/lONPXcLzs1yVERHhOmONyns"
Date: Tue, 28 Dec 2021 21:35:11 GMT
Connection: keep-alive
Keep-Alive: timeout=5

As You may see there is a part with “cache-control”.
My problem is that I cannot see any keys or values stored in Redis. I am connected to Redis server with redis-cli tool and Ive tried “KEYS ‘*’” command. There is nothing stored in Redis.

Also I have problem with more complex queries - I do not even get a header with “cache-control” part.

Do You have any idea what I am doing wrong here? Should I be able to see stored values in Redis with such approach?
Thank You in advance for any advice.
