Getting below error when trying to connect SQL Server Local database in **NodeJs** **Sequelize**.

Below are my configuration settings and the credentials are correct

```
    "use_env_variable": false,
    "username": "username",
    "password": "password@123",
    "database": "db_test",
    "host": "abcdd\\SQL2K12",  //actual db hotsname is abcdd\SQL2K12
    "dialect": "mssql",
    "operatorsAliases": false,
    "dialectOptions": {
      "encrypt": true,
      "trustedConnection": true
    }

```

In SSMS its working fine. And is there issue with port number? As I am not using a port in SSMS.
