If you are using the self-hosted version (community edition) of Dify, this is a known bug that has already been fixed in version 1.11.0 or later.

See:

• Optional file/file-list variables fail validation with "must be a list of files" error · Issue #28947 · langgenius/dify · GitHub
• fix: treat empty default values for optional file inputs as unset by yatotm · Pull Request #28948 · langgenius/dify · GitHub
