@dosubot[bot] commented on GitHub (Apr 1, 2025):

The issue you're experiencing with metadata filtering when using Chinese characters in label names is a known limitation in the Dify platform. Currently, files with Chinese characters in their filenames cannot be downloaded through Dify's download_url endpoint, and similar limitations might affect other functionalities like metadata filtering [1].

To work around this issue, try using English (ASCII) characters for label names in metadata filtering. This should allow you to add variables normally.

However, in chatflow, Chinese labels can be used as variables for knowledge summarization.
