Hi, thanks for the great plugin, it works great, but only on the first page load.

I'm trying to use it together with nuxt, put the code for getting photos in asyncData and everything works on the first page load, but when I go to another page I get the error

error => TypeError: The "listener" argument must be of type Function. Received type object
    at checkListener (events.js?faa1:72)
    at _addListener (events.js?faa1:169)
    at module.exports.addListener (events.js?faa1:227)
    at Object.http.request (index.js?9490:38)
    at Object.get (index.js?9490:43)
    at Object.https.get (index.js?24f8:17)
    at eval (index.js?61a9:25)
    at new Promise (<anonymous>)
    at Object.get (index.js?61a9:22)
    at eval (index.js?61a9:79)

here is my code

    async asyncData({ $axios, params, store, redirect }) {  
        let hashtag = null;
        try {
            const Insta = require("scraper-instagram");
            const InstaClient = new Insta();
            const yourSessionId = "my_session_id_from_cookie";
            const client = await InstaClient.authBySessionId(yourSessionId);
            hashtag = await InstaClient.getHashtag("some_hashtag");
        } catch (error) {
            console.log(`error =>`, error);
        }

        const data = {
            hashtag: hashtag,           
        };
        return data;
    },

after digging i found some strange, you use http.request wich get two arguments,

http.request = function (opts, cb) {}

but you pass three arguments url, headers, and callback

https.get(url, {
    headers: {
    	cookie: sessionId ? `sessionid=${sessionId}` : ''
    }
    }, res => {
    ...
    }
);

for some reason, headerss get into the callback

Hello,

Yes, the method can take two arguments options and callback, but it can also take three arguments url, options and callback, which I'm actually doing, see the documentation.

Apparently, the error you're experiencing can happen when when using on mehods (from EventEmitter), which is strange because the three listeners I use (data, end and error) are indeed called with a function as second argument.

Although, I'll continue investigating. In the meantime, do you think you could reproduce this bug outside of any framework so I can better understand it ?

Thanks.
