Dify version

0.13.1

Cloud or Self Hosted

Self Hosted (Docker)

Steps to reproduce

Using Attach button on a chatbot/chatflow with both options enabled: local upload or upload via URL. If you use URL, the sys.files0[].transfer_method is set with 'local_file'

"sys.files": [
    {
      "dify_model_identity": "__dify__file__",
      "id": null,
      "tenant_id": "fb5cc640-7ff7-4ad4-89b2-88f35e7441c4",
      "type": "document",
      "transfer_method": "local_file",
      "remote_url": "https://example.com/",
      "related_id": "6781620a-f6a5-4c8f-af69-d4abae7a292c",
      "filename": "c0188599-5f00-49ab-9d35-df5b20916fbf.bin",
      "extension": ".bin",
      "mime_type": "text/html; charset=UTF-8",
      "size": 1256,
      "url": "/files/6781620a-f6a5-4c8f-af69-d4abae7a292c/file-preview?timestamp=1734561710&nonce=e3083b50cad6590eceb87d0a0194a150&sign=jBn1FX-RKQCARv1vFrU1TUmT4cg7RpBxrNwYfAyx9Vw="
    }
  ],

If you want to use a list-operator block and use 'transfer_method' as a filter, it won't work because on both cases the transfer_method is 'local_file'. The other options available are not helping to filter if it's local upload or upload via URL:
Selection_304
one option could be "remote_url" but it's not available.

✔️ Expected Behavior

The value of 'transfer_method' should be remote_url.

❌ Actual Behavior

The value of 'transfer_method' is local_file (see https://github.com/langgenius/dify/pull/11207)

Hello, @rnavarroz! I'm here to assist with any bugs, questions, or contributions you have for the project. Let's tackle this issue together!

The issue you're experiencing with the transfer_method attribute being incorrectly set to local_file for both local uploads and URL uploads is acknowledged in the Dify codebase. The expected behavior is for the transfer_method to be set to remote_url when a file is uploaded via a URL. This discrepancy was addressed in GitHub pull request #11207, which proposed changes to correctly differentiate between local and remote uploads by removing the validation that caused this issue. This change has been merged into the main branch, so updating to the latest version of Dify should resolve the problem.
