❓ Question: How to Properly Pass crawler_params in n8n Node

[Mirindi]

Hi team! I'm trying to use Crawl4AI in an n8n workflow and struggling to pass the crawler_params object inside the request body.

Here's an example of what I'm trying to send:

{
  "request": {
    "urls": "{{ $('Loop Over Items').item.json['sitemapindex.sitemap'].loc }}",
    "crawler_params": {
      "headless": true,
      "browser_type": "chromium",
      "user_agent": "Mozilla/5.0 ...",
      "page_timeout": 30000,
      "verbose": true,
      "semaphore_count": 5,
      "simulate_user": true,
      "magic": true,
      "override_navigator": true,
      "user_data_dir": "./browser-data",
      "use_managed_browser": true,
      "headers": {
        "Accept-Language": "en-US,en;q=0.9"
      }
    }
  }
}

But n8n always throws a Failed on navigating ACS-GOTO :\nPage.goto: net::ERR_HTTP2_PROTOCOL_ERROR at https://www.carrefour.ke/sitemaps/clp_en.xml\nCall log:\nnavigating to "https://www.carrefour.ke/sitemaps/clp_en.xml", waiting until "domcontentloaded"\n error.

I’ve tried escaping the mustache template, building it in code, using a Function node, etc.—no luck. What is the correct way to dynamically pass crawler_params and urls into a Crawl4AI request from an n8n node?

Any guidance or examples would be super appreciated!

Thanks 🙏
