Dify version

1.12.1

Cloud or Self Hosted

Self Hosted (Docker)

Steps to reproduce

  1. Create a Workflow with User Input as start node
  2. In User Input, add a required file variable which accepts remote URL as upload method
  3. Click Test Run on this Workflow, Dify will asks to upload the file
  4. Copy and paste a remote file URL and then click OK
  5. Dify will show an error message "File upload failed". Check the API response in Developer Tools, we get a 500 Internal Server Error to endpoint POST /console/api/files/upload, and a message in response body: "current_user must be an Account instance"

Note: Upload from local files works perfectly.

✔️ Expected Behavior

Dify should support uploading by remote URL.

❌ Actual Behavior

Cannot upload files through remote URL during Workflow test run.

In the same environment, the URL returned for the uploaded file is inaccessible.
