Dify version

1.9.1

Cloud or Self Hosted

Cloud

Steps to reproduce

  1. Go to Dify Cloud (https://app.dify.ai) and create a new application.
  2. In Workflow, add a File input variable in Start node (Required = ON, Allowed types = image/document/other).
  3. Publish the application and open the public URL.
  4. Upload any file (tested with .png, .jpg, .pdf, .zip).
  5. The UI only shows a blank paper icon (no filename is displayed).
  6. Run the workflow → error occurs:
    No matching enum found for value 'None'

✔️ Expected Behavior

When I upload a file in the public application:

  • The filename should be displayed in the input field (instead of a blank icon).
  • The file object (name, type, url) should be passed correctly to the Start node.
  • The workflow should run without errors when a file is attached.

❌ Actual Behavior

No response
