Launch Module: Chrome + Relay + Playwright

Architecture

Windows Chrome (--remote-debugging-port=9222)
  ↕ Relay2.exe (0.0.0.0:9255 → 127.0.0.1:9222)
Windows IP (172.24.48.1:9255)
  ↕ WSL chrome_relay.py (127.0.0.1:19223 → 172.24.48.1:9255)
  ↕ Playwright connect_over_cdp('http://127.0.0.1:19223')

Step A: Launch Chrome (Windows)

# First kill old Chrome processes
taskkill /F /IM chrome.exe

# Start Chrome with debug port
cmd.exe /c start "" "C:\Program Files\Google\Chrome\Application\chrome.exe" \
  --remote-debugging-port=9222 \
  --user-data-dir="C:\Users\[Your Windows Username]\Desktop\chrome-debug"

⚠️ Must use a dedicated --user-data-dir (e.g., chrome-debug); the default profile cannot bind to port 9222.

Step B: Launch Relay2 (Windows)

Relay2.exe should run automatically at Windows startup: C:\Users\[Your Windows Username]\AppData\Roaming\Microsoft\Windows\Start Menu\Programs\Startup\hermes-gateway.vbs

To start manually: double-click Relay2.exe.

Step C: Start WSL Relay

cd ~/.hermes/scripts && python3 chrome_relay.py &

Step D: Verify the Chain

# Check WSL relay
curl -s http://127.0.0.1:19223/json | head -5

# Should return JSON list of Chrome tabs

Step E: Playwright Connection

from playwright.async_api import async_playwright

async with async_playwright() as p:
    browser = await p.chromium.connect_over_cdp('http://127.0.0.1:19223')
    pages = browser.contexts[0].pages
    # Check open tabs

Login Check

Dianxiaomi Login

Navigate to Dianxiaomi → verify if logged in (look for [Your Dianxiaomi Username] on the page):

document.body.innerText.includes('[Your Dianxiaomi Username]')

If not logged in, use QR code login: Dianxiaomi top-right corner → Scan QR code to log in.

1688 Login

Check 1688 login status: Open any 1688 product page → see if there is a "Log In" button.

document.body.innerText.includes('Log In')

If not logged in, log in manually (1688 CAPTCHA cannot be automated).

Failure Recovery

Gateway Disconnection Reconnection Rules

Fatal error: Directly calling browser_navigate creates a new tab, losing already-filled data.

Correct steps:

1. browser_cdp → Target.getTargets     # List all tabs
2. Find Dianxiaomi edit page (title="Dianxiaomi--Edit AliExpress Product")
3. Runtime.evaluate to read page state (title/hash/bodyText)
4. Confirm which tab has filled data
5. Target.closeTarget to close blank/duplicate tabs
6. Target.activateTarget to activate the correct tab
7. Now browser_snapshot should show filled data

Full Chain Down

# WSL side
pkill -f chrome_relay.py
cd ~/.hermes/scripts && python3 chrome_relay.py &

# Windows side (manually or triggered from WSL)
taskkill /F /IM chrome.exe
# Restart Chrome (Step A)
