Dify version

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.

And, i check this issus #26841 , and update my local git repo by this cmd :

git checkout main

git pull origin main

tar -cvf volumes-$(date +%s).tgz volumes

docker-compose down

docker-compose up -d

after all container started, open explore , still error No matching enum found for value 'None'

✔️ Expected Behavior

After a file is uploaded in the Explore chat interface, its name should be displayed in the box, confirming the upload.

❌ Actual Behavior

No response
