无法读取未定义的属性 'omitFormat'

Question

我在 clickhouse 中创建了一个 table，如下所示：

let clickhouse = new ClickHouse (sails.config.clickhouse);
let query = `CREATE TABLE table1(category String,subcategory String,title String,id Int64) Engine=Log`

我尝试运行上面的查询：

return new Promise((resolve, reject) => {
            clickhouse.query (query, function (err, result) {
                if (err) {
                    console.log(err);
                }
                resolve('success');
            });
        });
let test = await createTable();

但后来我得到了这个错误：

Cannot read property 'omitFormat' of undefined

这个错误有什么解决办法吗？谢谢

P.S：我已经尝试运行 Clickhouse 客户端中的查询并且有效。

你传的没有初始化sails.config.clickhouse-param.

传递未定义的 options to ClickHouse-constructor leads to the error in this line。

查看控制台可以看到相关警告：

重现此错误的代码（参见 https://repl.it/repls/FakePortlyExponent）：

const ClickHouse = require('@apla/clickhouse')

let clickhouse = new ClickHouse (/*sails.config.clickhouse*/null); // <----- !!!
let query = `CREATE TABLE table1(category String,subcategory String,title String,id Int64) Engine=Log`;

async function createTable() {
  return new Promise((resolve, reject) => {
              clickhouse.query (query, function (err, result) {
                  if (err) {
                      console.log(err);
                  }
                  resolve('success');
              });
          });
}

createTable()
    .then(() => {
        console.info('Success.');
    })
    .catch(err => {
        console.error('Error:', err);
    });
