Script runs smoothly from start to finish, but the expected result doesn't happen

Question

The project aims to study a new social media:

https://booyah.live/

My needs are:

1 - Collect data from profiles that follow a specific profile.

2 - My account use this data to follow the collected profiles.

3 - Among other possible options, also unfollow the profiles I follow.

The problem found in the current script:

The profile data in theory is being collected, the script runs perfectly until the end, but for some reason I can't specify, instead of following all the collected profiles, it only follows the base profile.

For example:

I want to follow all 250 profiles that follow the ID 123456

I activate the booyahGetAccounts(123456); script

In theory the end result would be my account following 250 profiles

But the end result I end up following only the 123456 profile, so the count of people I'm following is 1

I have to admit that it is really hard to read your code, I spent a lesser amount of time rewriting everything from scratch.

Stated that we need a code piece to be cut/pasted in the JavaScript console of web browsers able to store some data (i.e. expiration of followings and permanent followings) we need some considerations.

We can consider expiration of followings as volatile data: something that if lost can be reset to 1 day later from when we loose this data. window.localStorage is a perfect candidate to store these kind of data. If we change web browser the only drawback is that we loose the expiration of followings and we can tolerate to reset them to 1 day later from when we change browser.

While to store the list of permanent followings we need a permanent store even if we change web browser. The best idea that came to my mind is to create an alternative account with which to follow the users we never want to stop following. In my code I used uid 3186068 (a random user), once you have created your own alternative account, just replace the first line of the code block with its uid.

Another thing we need to take care is error handling: API could always have errors. The approach I chosen is to write myFetch which, in case of errors, retries twice the same call; if the error persists, probably we are facing a temporary booyah.live outage. Probably we just need to retry a bit later.

To try to provide a comfortable interface, the code blocks gathers the uid from window.location: to follow the followers of users, just cut/paste the code block on tabs opened on their profiles. For example I run the code from a tab open on https://booyah.live/studio/123456?source=44.

Last, to unfollow users the clean function is called 5 minutes later we paste the code (to not conflict with calls to follow followers) and than is executed one hour later it finishes its job. It is written to access the localStorage in an atomic way, so you can have many of them running simultaneously on different tabs of the same browser, you can not care about it. The only thing you need to take care it that when the window.location changes, all the JavaScript events in the tab are reset; so I suggest to keep a tab open on the home page, paste the code block on it, and forget about this tab; it will be the tab responsible of unfollowing users. Then open other tabs to do what you need, when you hit a user you want to follow the followers, paste the block on it, wait the job is finished and continue to use the tab normally.

// The account we use to store followings
const followingsUID = 3186068;
// Gather the loggedUID from window.localStorage
const { loggedUID } = window.localStorage;
// Gather the CSRF-Token from the cookies
const csrf = document.cookie.split("; ").reduce((ret, _) => (_.startsWith("session_key=") ? _.substr(12) : ret), null);

// APIs could have errors, let's do some retries
async function myFetch(url, options, attempt = 0) {
  try {
    const res = await fetch("https://booyah.live/api/v3/" + url, options);
    const ret = await res.json();

    return ret;
  } catch(e) {
    // After too many consecutive errors, let's abort: we need to retry later
    if(attempt === 3) throw e;

    return myFetch(url, option, attempt + 1);
  }
}

function expire(uid, add = true) {
  const { followingsExpire } = window.localStorage;
  let expires = {};

  try {
    // Get and parse followingsExpire from localStorage
    expires = JSON.parse(followingsExpire);
  } catch(e) {
    // In case of error (ex. new browsers) simply init to empty
    window.localStorage.followingsExpire = "{}";
  }

  if(! uid) return expires;

  // Set expire after 1 day
  if(add) expires[uid] = new Date().getTime() + 3600 * 24 * 1000;
  else delete expires[uid];

  window.localStorage.followingsExpire = JSON.stringify(expires);
}

async function clean() {
  try {
    const expires = expire();
    const now = new Date().getTime();

    for(const uid in expires) {
      if(expires[uid] < now) {
        await followUser(parseInt(uid), false);
        expire(uid, false);
      }
    }
  } catch(e) {}

  // Repeat clean in an hour
  window.setTimeout(clean, 3600 * 1000);
}

async function fetchFollow(uid, type = "followers", from = 0) {
  const { cursor, follower_list, following_list } = await myFetch(`users/${uid}/${type}?cursor=${from}&count=50`);
  const got = (type === "followers" ? follower_list : following_list).map(_ => _.uid);
  const others = cursor ? await fetchFollow(uid, type, cursor) : [];

  return [...got, ...others];
}

async function followUser(uid, follow = true) {
  console.log(`${follow ? "F" : "Unf"}ollowing ${uid}...`);
  return myFetch(`users/${loggedUID}/followings`, {
    method:  follow ? "POST" : "DELETE",
    headers: { "X-CSRF-Token": csrf },
    body:    JSON.stringify({ followee_uid: uid, source: 43 })
  });
}

async function doAll() {
  if(! loggedUID) throw new Error("Can't get 'loggedUID' from localStorage: try to login again");
  if(! csrf) throw new Error("Can't get session token from cookies: try to login again");

  console.log("Fetching current followings...");
  const currentFollowings = await fetchFollow(loggedUID, "followings");

  console.log("Fetching permanent followings...");
  const permanentFollowings = await fetchFollow(followingsUID, "followings");

  console.log("Syncing permanent followings...");
  for(const uid of permanentFollowings) {
    expire(uid, false);

    if(currentFollowings.indexOf(uid) === -1) {
      await followUser(uid);
      currentFollowings.push(uid);
    }
  }

  // Sync followingsExpire in localStorage
  for(const uid of currentFollowings) if(permanentFollowings.indexOf(uid) === -1) expire(uid);
  // Call first clean task in 5 minutes
  window.setTimeout(clean, 300 * 1000);

  // Gather uid from window.location
  const match = /\/studio\/(\d+)/.exec(window.location.pathname);

  if(match) {
    console.log("Fetching this user followers...");
    const followings = await fetchFollow(parseInt(match[1]));

    for(const uid of followings) {
      if(currentFollowings.indexOf(uid) === -1) {
        await followUser(uid);
        expire(uid);
      }
    }
  }

  return "Done";
}

await doAll();

The problem: I strongly suspect a booyah.live API bug

To test my code I run it from https://booyah.live/studio/123456?source=44.

If I run it multiple times I continue to get following output:

Fetching current followings...
Fetching permanent followings...
Syncing permanent followings...
Following 1801775...
Following 143823...
Following 137017...
Fetching this user followers...
Following 16884042...
Following 16166724...

There is bug somewhere! The expected output for subsequent executions in the same tab would be:

Fetching current followings...
Fetching permanent followings...
Syncing permanent followings...
Fetching this user followers...

After seeking the bug in my code without success, I checked booyah.live APIs: if I navigate following URLs (the uids are the ones the code continue to follow in subsequent executions)

https://booyah.live/studio/1801775
https://booyah.live/studio/143823
https://booyah.live/studio/137017
https://booyah.live/studio/16884042
https://booyah.live/studio/16166724

I can clearly see I follow them, but if I navigate https://booyah.live/following (the list of users I follow) I can't find them, neither if I scroll the page till the end.

Since I do exactly the same calls the website does, I strongly suspect the bug is in booyah.live APIs, exactly in the way they handle the cursor parameter.

I suggest you to open a support ticket to booyah.live support team. You could use the test account you provided us: I already provided you the details to do that. ;)
