Redis Enterprise Clustering Command Error 'CLUSTER'

Question

We just installed Redis Enterprise and set some configuration on the database.

We create a simple script becase on our app the cluster command doesn't work, and that's correct it doesn't work:

var RedisClustr = require('redis-clustr');
var redis = new RedisClustr({
  servers: [
    {
      host: 'URL',
      port: 18611
    }
  ],
  redisOptions: {
    password: 'ourpassword'
  }
});

redis.get('KSHJDK', function(err, res) {
  console.log(res, err);
});

Error on the shell:

undefined Error: couldn't get slot allocation'

      command: 'CLUSTER',
      args: [Array],
      code: 'ERR'
    }
  ]
}

Are we missing something on the configuration? We don't know if its an error con the clustering or on Redis Enterprise.

Redis Enterprise supports two clustering flavors. With regular OSS cluster you need a cluster aware client like the one you use. The one you are using is for non-cluster aware clients, you should use it with regular client (as if you are connecting to a single Redis process).
