Question

A specific question, so it’s understandable to anyone. You may add pictures.

YOUR QUESTION HERE I was working on this function, it’s bassed on the given example in docs:

require("dotenv").config();
const fs = require('fs');
const { IgApiClient } = require("instagram-private-api");
const ig = new IgApiClient();
const username = process.env.IG_USERNAME;
const password = process.env.IG_PASSWORD;
ig.state.generateDevice(username);

const dataCheck = function (callback) {
  fs.readFile('login_data.json', function (err, data) {
    console.log(data);
    if (data.length > 0) {
      callback(true);
    } else {
      callback(false);
    }
  });
}

const dataLoad = function (callback) {
  fs.readFile('login_data.json', function (err, data) {
      console.log("Read JSON file: " + data);
      data = JSON.parse(JSON.stringify(data));
      console.log("Object: " + data);
      callback(data);
  });
}

function dataSave(data){
  console.log("saving...");
  fs.writeFile("login_data.json", JSON.stringify(data),    function(err) {
    if(err) {
      console.log(err);
    }
    console.log("The file was saved!");
  }); 
}

igLogin();

async function igLogin(){

  await ig.simulate.preLoginFlow();

  ig.request.end$.subscribe(async () => {
    const serialized = await ig.state.serialize();
    delete serialized.constants;
    dataSave(serialized);
  });
  
  dataCheck(async dataExists => {
    console.log(dataExists);
    if (dataExists){
      dataLoad(async data => {
        ig.state.deserialize(data);
      }); 
    }
  });

  const auth = await ig.account.login(username, password);
  console.log(auth);
  
  process.nextTick(async () => await ig.simulate.postLoginFlow());

}

It can save the login data as a json file, It can login, but on the Instagram login activity it appears as a new login activity and not an old session. So, where is the mistake?

Hi, I had the same issues that load session returns Cookie "ds_user_id" not found. I found it because I changed the API version in core/constants.js; it won’t return the cookies in session. Replace APP_VERSION with “121.0.0.29.119” and APP_VERSION_CODE with “185203708” and create a session again. I hope this helps you guys.
