Hello, I'm getting the following error when I run the code below:

const Insta = require("@kaki87/ig-scraper");
const InstaClient = new Insta();
// The following line throws the error
InstaClient.subscribeUserPosts('cyanidehappinessvf2').subscribe({
    next: shortcode => {
        console.log(shortcode);
    },
    error: err => {
        console.error(err);
    }
});

It says that the error comes from the index.js, line 44. I updated the code like this (I added a console.log):

When it works

I used a VPN to make the code working again, here is the console.log(data); result:

After removing my VPN, here is the result:

{

}

If you need further information, I'm available and I can make tests for you, if you cannot reproduce the bug.

I finally managed to reproduce your issue, after spamming Instagram with a hell of requests !

In fact, you're being redirected to Instagram's login page.

This behavior generally occurs when trying to authenticate using InstaClient.authBySessionId() with an invalid or expired session ID (i.e. HTTP 401).

In this case, however, it seems to be a reaction to spam (i.e. HTTP 429), unfortunately, I can't distinguish these two, so I made a fix that will do nothing more but detect the redirection and return a 401 error.

Anyway, using a VPN works as a bypass solution, while authenticating doesn't.

Thanks for reporting.
