Dify version

1.9.1

Cloud or Self Hosted

Self Hosted (Docker)

Steps to reproduce

Steps to reproduce the behavior:

  1. Create and publish a workflow in the Studio that requires a file upload as input.
  2. Go to the Explore section.
  3. Open the chat interface for the newly published workflow.
  4. Click the upload button and select a file (e.g., a .txt or .pdf file).
  5. Observe: The file seems to upload, but its name does not appear in the input field.
  6. Try to send the message to run the workflow.
  7. Observe: The error No matching enum found for value 'None' is returned.

✔️ Expected Behavior

  1. After a file is uploaded in the Explore chat interface, its name should be displayed in the box, confirming the upload.
  2. The workflow should run successfully using the uploaded file, without any errors, just as it does in the Chatflow and Studio environments.

❌ Actual Behavior

When I use the chat interface for a published workflow in the Explore section, after uploading a file, two issues occur:
The filename is not displayed in the chat input box.
When I try to run the workflow with the uploaded file, it fails with the error message: No matching enum found for value 'None'.
Interestingly, this functionality works perfectly fine in the standard Chatflow and within the Studio when testing the workflow. The issue seems to be isolated to the public-facing "Explore" chat interface.
