⚠️ Known Issues (January 2025)

🐛 DuckDuckGo Library Compatibility Issue

Status: ACTIVE ISSUE - Affects Web Search operation

• Problem: DuckDuckGo has changed their website structure, causing the underlying duck-duck-scrape library to fail with error: "Cannot read properties of null (reading '1')"
• Impact: Web Search returns empty results or errors
• Cause: The library's regex patterns no longer match DuckDuckGo's new HTML structure
• Affected Operations: Primarily Web Search (other operations may still work)
• Timeline: This is an upstream library issue affecting many users globally

🔧 Current Workarounds

1. Try Alternative Operations: Image Search, News Search, and other operations may still work
2. Use Different Queries: Sometimes simpler queries work better
3. Report Issues: Help us track which queries fail by reporting issues
4. Check Updates: We're monitoring for duck-duck-scrape library updates

🎯 Resolution Status

• Tracking: Issue is being tracked in the duck-duck-scrape repository
• Alternative Solutions: We're investigating SearchAPI.io and other alternatives
• Updates: This README will be updated when a fix is available
