I am using nightly build 2026.01.06.233142 of yt-dlp and also installed pip install "yt-dlp[default,curl-cffi]". When I use impersonate I got error. how to fix the error.

import yt_dlp
import json
import sys

# 1. Verify curl-cffi exists (Required for --impersonate)
try:
    import curl_cffi
except ImportError:
    print("Error: 'curl-cffi' is missing. Impersonation will not work.", file=sys.stderr)
    print("Fix: Run 'pip install \"yt-dlp[default,curl-cffi]\"'", file=sys.stderr)
    sys.exit(1)

url = "https://www.youtube.com/watch?v=somerandomid"

ydl_opts = {
    'quiet': True,
    'verbose': True, 
    'format': 'best',
    'js_runtimes':{'deno': {}},
    'impersonate': "chrome-116:windows-10",
    'simulate': True, 
    'skip_download': True,
    'noplaylist': True,
}

try:
    with yt_dlp.YoutubeDL(ydl_opts) as ydl:
        # Extract metadata
        meta = ydl.extract_info(url, download=False)
        
        # Safe extraction with defaults
        formats = meta.get('formats', [])
        duration = meta.get('duration')
        thumbnail = meta.get('thumbnail')
        title = meta.get('title')

        output_data = []
        for item in formats:
            if item.get('audio_ext') != 'none':
                # Add metadata to the specific format object
                item.update({'duration': duration, 'thumbnail': thumbnail, 'title': title})
                output_data.append(item)
                break
            
        print(json.dumps(output_data))

except yt_dlp.utils.DownloadError as e:
    # Specific check for impersonation target errors
    if "Impersonate target" in str(e):
        print(f"FAILED: The impersonate target '{ydl_opts['impersonate']}' is invalid or unsupported by your curl-cffi version.")
    else:
        print(f"yt-dlp download error: {e}")
except Exception as e:
    print(f"General error: {e}")
