🔧 Need a programmer (Node.js) — repair of the existing Chrome CDP program

There is a ready Windows program that has been working for months but suddenly broke without any code changes.

What the program does:
It sequentially opens real Chrome profiles, goes to threeplus.three.co.uk, clicks Get Reward → My Codes, reads 1 code, and saves it in CSV. It works one-by-one, without parallel runs.

Problem:
After the first Chrome profile does not close physically, chrome.exe remains, and the next run fails with:

Protocol error (Target.setAutoAttach): Target closed

Already checked (this is NOT the reason):

JSON / config / number of profiles
maxProcessCount
rewards_url / site logic
antivirus / Defender
Chrome path / compatibility of chrome.exe
temporary clean profile works
the program worked yesterday without changes

Task:
Fix correct shutdown of Chrome / CDP, without rewriting the program.

❌ Selenium / headless / proxy
✅ Real Chrome, CDP, existing profiles

💸 I expect a low-cost implementation
(including — because the site changes several times a month — I will regularly contact you for payment for minor adjustments).

Below is part of the original order when I ordered the program.

🎯 Goal

Create a desktop program (in Python or Node.js) that automatically opens real Chrome profiles, logs into 20 Three+ accounts, clicks Get Reward, goes to My Codes, extracts the code in the form of TH3DC\d{9,} and adds it to the corresponding row in CSV.

⚙️ Functionality

Runs manually on Windows (without auto-start or services).
Works through real Chrome with local profiles (user-data-dir + profile-directory).
Does not use headless mode, Selenium, HTTP requests, or proxies.
Simulates human actions: launching the browser, clicking, navigating, pausing.
Processes up to 20 accounts per run (specified in the config).
Skips accounts where the code is already in CSV.

🔄 Workflow Algorithm

Step 1: Load Configuration

Reads settings.json (chrome path, list of profiles, CSV path, delays).
Reads CSV, identifies accounts without codes.

Step 2: Process Each Profile

Launches Chrome with the specified profile:

iniCopyEdit--user-data-dir=<user_data_dir>

--profile-directory=<profile_dir>

--remote-debugging-port=9222

Connects via CDP (Playwright or Puppeteer).
Opens rewards_url.
Waits for the page to fully load.
Clicks the Get Reward button (with a valid click, not .click()): valid click (via Playwright/Puppeteer with mouse.move + mouse.down + mouse.up, without .click()).
Waits 3–5 seconds.

Step 3: Read Code from My Codes

Goes to the page https://threeplus.three.co.uk/my-rewards
(or clicks Go to my codes if it appeared after Get Reward).
Searches for the last code in the format TH3DC\d{9,} in the DOM (via innerText / textContent).
Saves in CSV as:
```
CopyEditProfile_01,TH3DC103897998490
```
Closes the browser (but does not log out).
Waits a random delay (20–40 seconds).
Repeats for up to 20 accounts.

🧠 How the code is read (clear algorithm)

OCR, screenshots, and modal windows are not used.
The code is always read from the My Codes page - after clicking "Get Reward"
Code format: TH3DC103897998490 (pattern: TH3DC\d{9,}).
Reading: through DOM (innerText, textContent, evaluate()).

⚙️ Configuration (settings.json)

jsonCopyEdit{

  "chrome_path": "C:\\Program Files\\Google\\Chrome\\Application\\chrome.exe",

  "profiles": [

    {

      "user_data_dir": "C:\\Users\\User\\AppData\\Local\\Google\\Chrome\\User Data",

      "profile_dir": "Profile 1"

    }

    // ...

  ],

  "rewards_url": "https://threeplus.three.co.uk/rewards",

  "csv_path": "C:\\path\\to\\accounts.csv",

  "delay_range_seconds": [90, 240]

}

📄 CSV Format

Need a programmer (Node.js) - repair of the existing Chrome CDP program - which I made here for $34

What has already been checked and is NOT the cause:

JSON / config:
maxProcessCount, rewards_url, chrome_path, csv_path — correct.
Changes in JSON do not affect remote_debugging_port (the code does not account for it).
Antivirus / Defender / Firewall:
Disabled, not blocking.
Ports checked — no conflicts.
Chrome:
Path is correct, clean profile launches.
Manual launch with --user-data-dir works → Chrome itself is okay.
Remote debugging ports:
9222 is unstable, others (9223+, 9333) work manually.
The program does not connect to http://localhost:<port>/json → CDP does not open.
Launching/closing Chrome through the program:
First profile is okay.
After that — hanging Chrome process and error:
Protocol error (Target.setAutoAttach): Target closed.
Three+ site:
Logic has not changed, works manually.

Key new factor:

The problem started after the Chrome update, meaning most likely the update changed:

behavior --remote-debugging-port
process start time
CDP-attach policy
or requirements for flags/arguments.

Brief conclusion for the programmer:

The program configuration is normal.
The main problem is in the way of launching and connecting to Chrome via CDP.
After the last Chrome update, the behavior of --remote-debugging-port changed, and the program either does not wait for a stable start or closes the process incorrectly.

So now:

CDP does not manage to open
hanging Chrome processes block subsequent profiles

and the following appears:

Target.setAutoAttach → Target closed.

Потрібен програміст (Node.js) - ремонт існуючої Chrome CDP програми - яку я зробив тут за $34

Що вже перевірено та НЕ є причиною:

JSON / config:
maxProcessCount, rewards_url, chrome_path, csv_path — коректні.
Зміни в JSON не впливають на remote_debugging_port (код не враховує).
Антивірус / Defender / Firewall:
Вимкнені, не блокують.
Порти перевірені — конфліктів немає.
Chrome:
Шлях правильний, чистий профіль запускається.
Ручний запуск з --user-data-dir працює → сам Chrome ок.
Remote debugging ports:
9222 нестабільний, інші (9223+, 9333) працюють вручну.
Програма не підключається до http://localhost:<port>/json → CDP не відкривається.
Запуск/закриття Chrome через програму:
Перший профіль ок.
Далі — завислий Chrome процес і помилка:
Protocol error (Target.setAutoAttach): Target closed.
Сайт Three+:
Логіка не змінювалась, вручну працює.

Ключовий новий фактор:

Проблема почалася після оновлення Chrome, тобто найбільш ймовірно update змінив:

behavior --remote-debugging-port
час старту процесу
політику CDP-attach
або вимоги до flags/аргументів.

Стислий висновок для програміста:

Конфігурація програми в нормі.
Основна проблема — у способі запуску та підключення до Chrome через CDP.
Після останнього оновлення Chrome змінилась поведінка --remote-debugging-port, і програма або не чекає стабільного старту, або неправильно закриває процес.

Тому зараз:

CDP не встигає відкритись
завислі процеси Chrome блокують наступні профілі

і з’являється:

Target.setAutoAttach → Target closed.

Hi there,

I can help you quickly fix the Chrome CDP shutdown issue without rewriting your program or changing the existing architecture. I have hands-on experience with Node.js, Puppeteer/Playwright over CDP, and managing real Chrome profiles on Windows, including proper process lifecycle handling.

My approach will focus on identifying why chrome.exe is not terminating correctly, fixing the CDP detach and browser close sequence, and ensuring each profile fully shuts down before the next one starts. This will resolve the Target closed error while keeping your current logic, delays, and human-like behavior intact.

Estimated time: 1–3 days
Cost: low-cost, fixed price (we can agree upfront)
Availability: can start immediately and available for future small fixes as the site changes
…
I’m comfortable with ongoing minor adjustments on a pay-per-task basis and keeping the tool stable long term.

If you’d like, I can start with a quick diagnostic and confirm the exact fix before proceeding.

Best regards
