const { I } = inject();

const username = {id:'username'};
const password = {id:'password'};
const submitbtn = {id:'login'};

**import config from 'config';**

module.exports=
{
loginAsFaculty() {
console.log("Inside login")
I.amOnPage(config.get("baseUrl"))
I.fillField(username, config.get("slpEditUser.username"));
I.fillField(password, config.get("slpEditUser.password"));
I.click(submitbtn);
}

```js
// paste test
```

### Details
If I convert the import into require(common.js), then the error is gone.

Please plan to support ES6.
