Original Pull Request: https://github.com/langgenius/dify/pull/12114

State: closed
Merged: No

Summary

When uploading files or documents directly to a large model, serialization warnings may occur due to type mismatches. This happens because, in Pydantic v2, the model_dump method expects strict type matching for fields.Currently, the type is explicitly defined as List, so using List reduces potential type mismatch issues and improves code readability.
