Nightwatch: ES6 async/awaits browser.elements() resolves Nightwatch API

[ioedeveloper]

Describe the bug

Async/awaits with browser.elements function returns Nightwatch API instead of array of web elements.

Sample test

sampleTest.js

const EventEmitter = require('events')

class sampleTest extends EventEmitter {
  async command () {
    const browser = this.api
    const result = await browser.elements('css selector', '*[data-id="selector"]')

    console.log('result: ', result) //logs Nightwatch API to console
    // result.value is undefined
    result.value.forEach(async function (jsonWebElement) {
      const jsonWebElementId = jsonWebElement.ELEMENT
    })
    this.emit('complete')
    return this
  }
}

module.exports = sampleTest

Run with command

$ nightwatch test/sampleTest.js --your-other-arguments-here

Verbose output

debug.log

Running: sampleTest

Result: TypeError: Error while running "sampleTest" command: Cannot read property 'forEach' of undefined

Configuration

nightwatch.json

{
  "your": { "config": "here" }
}

Your Environment

| nightwatch --version | 1.3.4 |
| npm --version | 6.9.0 |
| node --version | 10.16.2 |
| selenium-server | 3.141 |
| Ubuntu | 18.04 |

It should be said that this only happens when writing custom commands.

The same also applies to browser.getText() when writing custom commands.

I'm facing the same issue when using const result = await this.api.getLocationInView('xpath', selector); inside a custom assertion.

Has anyone had any luck finding a workaround for this?

Depending on context, I am also also encountering cases where the whole call becomes async and returns, despite the use of await.

Using the command above, and something like:

const res = await browser.command()
browser.perform(() => { console.log('after command') })

I get output:

after command
[...]
result

Same if I do the below, copied from https://nightwatchjs.org/api/getWindowSize.html

const value = await browser.getWindowSize();
console.log('value', value);
