- Updated firecrawl_search tool schema to accept both string format (["web"]) and object format ([{"type": "web"}])
- Added normalization logic to convert string formats to object format internally
- Updated documentation to show both supported formats
- Fixes HTTP 422 error when using string format for sources parameter
- Maintains backward compatibility with existing implementations
Resolves issue where requests with sources: ["web"] would fail with:
HTTP error 422: {"detail":[{"type":"model_attributes_type","loc":["body","sources",0],"msg":"Input should be a valid dictionary or object to extract fields from","input":"web"}]}

Bug Fix: Sources Parameter Schema Validation
Problem
The
firecrawl_searchtool had a mismatch between documentation and implementation:sourcesas an array of strings:["web"]sourcesas an array of objects:[{type: "web"}]This caused HTTP 422 errors when using the string format:
{ "error": "HTTP error 422: {\"detail\":[{\"type\":\"model_attributes_type\",\"loc\":[\"body\",\"sources\",0],\"msg\":\"Input should be a valid dictionary or object to extract fields from\",\"input\":\"web\"}]}" }Solution
Changes
sourcesparameter schema infirecrawl_searchtoolTesting
✅ Both formats now work correctly:
sources: ["web"]sources: [{"type": "web"}]Backward Compatibility
This change is fully backward compatible - existing code using either format will continue to work.
