Original Pull Request: https://github.com/langgenius/dify/pull/20072

State: closed
Merged: Yes


Summary

A separate PR (#20063) failed due to the introduction of missing boto3 type stubs. These stubs surfaced a potential type mismatch between S3StorageConfig.S3_ADDRESS_STYLE and what boto3 expects in the following line:

https://github.com/langgenius/dify/blob/d31235ca134ca6b9d52f969a2309ef898d7fe773/api/extensions/storage/aws_s3_storage.py#L35

extensions/storage/aws_s3_storage.py:35: error: Incompatible types (expression has type "str", TypedDict item "addressing_style" has type "Literal['auto', 'virtual', 'path']")  [typeddict-item]

This PR includes a proposed fix for the mypy error, but it’s only one possible solution. Feel free to modify or approach the fix differently if needed.
