strawpoll.get(...).then is not a function

[someretical]

I am using the example provided to create a strawpoll:

const strawpoll = require('strawpoll');
    let poll = strawpoll.create({
        title: 'My first poll',
        options: [
            'wow',
            'awesome',
            'amazing',
            'nice'
        ],
        multi: false,
        captcha: true
    }).then(response => {
        console.log(response);
    }).catch(err => {
        console.log(err);
    });

However it keeps on throwing:

TypeError: strawpoll.get(...).then is not a function

in my console
