使用nodejs中的n1ql进行Couchbase查询

Question

var N1qlQuery = require('couchbase').N1qlQuery;
var couchbase = require("couchbase");
var cluster = new couchbase.Cluster('host');
var bucket = cluster.openBucket('default');
 bucket.enableN1ql('host');



var query = N1qlQuery.fromString('SELECT * from default');
bucket.query(query, function(err, res){
  if (err) {
    console.log('query failed', err);
    return;
  }
  console.log('success!', res);
});

无法查询。将错误视为
