TypeError when trying to subscribeUserPosts()

I get these errors when i'm trying to subscribe with the function subscribeUserPosts().

When I start the program I get this error once:

TypeError: Cannot read property 'findIndex' of null
    at C:\Users\admin\Documents\GitHub\project\node_modules\scraper-instagram\index.js:437:46
    at processTicksAndRejections (internal/process/task_queues.js:97:5)

And then I get this when the account that i want to subscribe to has posted something:

TypeError: Cannot read property 'edges' of undefined
    at C:\Users\admin\Documents\GitHub\project\node_modules\scraper-instagram\index.js:290:46
    at processTicksAndRejections (internal/process/task_queues.js:97:5)

I don't really know what's happening

At index.js:437 :

const lastPostIndex = profile.lastPosts.findIndex(post => post.shortcode === lastPostShortcode);

The error :

Cannot read property 'findIndex' of null

As the documentation stipulates :

lastPosts array of posts - last posts
This property is empty ([]) when the profile doesn't have any post but null if access is false (denied).

And :

access boolean - access to the profile's feed

Conclusion : the subscribed profile is private and either you are not logged in to your Instagram account or you are not following the subscribed profile.

At [`index.js:437`](https://git.kaki87.net/KaKi87/ig-scraper/src/branch/master/index.js#L437) : ```js const lastPostIndex = profile.lastPosts.findIndex(post => post.shortcode === lastPostShortcode); ``` The error : > `Cannot read property 'findIndex' of null` As the documentation stipulates : > `lastPosts` *array of posts* - last posts This property is empty (`[]`) when the profile doesn't have any post but `null` if `access` is `false` (denied). And : > `access` *boolean* - access to the profile's feed Conclusion : the subscribed profile is private and either you are not logged in to your Instagram account or you are not following the subscribed profile.

Yes, thank you for responding so quick.

But I checked before if I was logged in and if I followed the account I wanted to "subrscribe" to. In fact even logged in, I can't use subscribeUserPosts() for any private account. Even though I am logged in.
I can see my profile with the this: ...but the error is still the same

InstaClient.authBySessionId(sessionid)
    .then(account => console.log(account))
    .catch(err => console.error(err));

I checked everything and the error didn't change.

I also discovered two other things:

When I try to "subscribe" to a public account it seems to work at first, but then when a new post is detected, I just get undefined in the console instead of the post information.
The shortcodes for private accounts are not supported in the getPost() function. I i try, I one of the errors I got yesterday:

TypeError: Cannot read property 'edges' of undefined
    at C:\Users\admin\Documents\GitHub\project\node_modules\scraper-instagram\index.js:290:46
    at processTicksAndRejections (internal/process/task_queues.js:97:5)

Thanks for the time and help!

Alright, investigating now.

Regarding subscribing public profiles though, I have a Discord bot running 24/7 which is simultaneously subscribed to 3 profiles and reposting their posts on a public community server, and it's been working fine for months now.

Although I can't reproduce the public profile issue, I can reproduce the getPost() issue with private profiles.

Working on it.

So, I actually forgot a very small detail xD (44b34d59)
Accessing post from followed private profiles is now working.

Ok I just found out why I couldn't get the posts. It was dumb from me: In the documentation and in my code, for subscribeUserPosts(), there was:

InstaClient.subscribeUserPosts(username, (post, err) => {
    if(post)
        console.log(post.shortcode);
    else
        console.error(err);
}, {
    interval,
    lastPostShortcode,
    fullPosts
});

but ther is no shortcode in post, so post.shortcode === undefined is always true
but there is post.link

Okay, feel free to close this issue if everything is fixed. :)
Then, I'll make an NPM release.

I just have another issue, but it's not critical for me. I tried using the functions subscribeUserPosts() for a private user but it does not work. The function getProfile() shows lastPosts: null for a private user I should be following.
Maybe I am doing things wrong.
Anyways thanks!

Oh, you mean no access while logged in?

That's very weird.

Can you show me the code?

Are you coding JS for the first time ?

The issue is that all your requests are executed at the same time without waiting for each other.

Here you go :

const
    { instaSessionid: sessionId } = require('./config'),
    shortcode = 'CG3FrMnrTUKObPfAIVaAS1OeikUyHS-enHipUE0',
    username = 'ljrdiscordbot';

const Insta = require('scraper-instagram');

const InstaClient = new Insta();

InstaClient
    .authBySessionId(sessionId)
    .then(account => {
        console.log(account);
        InstaClient
            .getPost(shortcode)
            .then(console.log)
            .catch(console.error);
        InstaClient
            .getProfile(username)
            .then(console.log)
            .catch(console.error);
    })
    .catch(console.error);

Yeah thank you very much!
I'm pretty new to programming in general and I try to learn everything alone(no ones teaches me how to do it).
Now seeing your answer it seems logical. Does it have something to do with async functions? I think I need to learn the syntax :)

Yes, the async/await syntax is also useful.
But you need to learn about promises first.
