Dify version

1.1.0

Cloud or Self Hosted

Self Hosted (Docker)

Steps to reproduce

When locally upload the image at start node, the following node cannot get the url property from variable.

✔️ Expected Behavior

No response

❌ Actual Behavior

start node output as follow:

{
  "sketch": {
    "dify_model_identity": "__dify__file__",
    "id": null,
    "tenant_id": "c7086304-4e22-44b1-90dd-a541aad38b10",
    "type": "image",
    "transfer_method": "local_file",
    "remote_url": "",
    "related_id": "ad1a975b-a3d2-4027-9098-e4a9b9d920fd",
    "filename": "sketch.png",
    "extension": ".png",
    "mime_type": "image/png",
    "size": 6695,
    "url": "/files/ad1a975b-a3d2-4027-9098-e4a9b9d920fd/file-preview?timestamp=1742431090&nonce=959184f1a477cc9570da978c441e1065&sign=iOUcBCh23MV8Nb4PB2vi52Ro3skIeuyc6dRRTQAAP2s="
  },
  "sys.query": "1",
  "sys.files": [],
  "sys.conversation_id": "3c809b6f-c30a-44f5-a22d-18fa5c8f9330",
  "sys.user_id": "8c37c467-7fc0-4e41-8219-a60a91f80d34",
  "sys.dialogue_count": 0,
  "sys.app_id": "cc6c4a85-66ee-4e97-94be-2637a6369bea",
  "sys.workflow_id": "91a01099-477b-4b38-9750-edd57f78a472",
  "sys.workflow_run_id": "3ea191c0-6147-43a4-aeee-5c63b33cb341"
}

But in the following node:

def main(url: str) -> dict:
    return {
        "result": url
    }

output is null:

Image

It seems that following node cannot get the url property?

@dosubot[bot] commented on GitHub (Mar 19, 2025):

I found a similar closed issue where users were unable to retrieve the URL variable from a file in a self-hosted Dify setup using Docker. The solution involves ensuring that the environment variables are correctly loaded from the .env file or directly set in the docker-compose.yaml file. Here's a snippet that demonstrates how to load these variables using DifyConfig and verify their values:

def test_flask_configs(example_env_file):
    flask_app = Flask("app")
    os.environ.clear()
    flask_app.config.from_mapping(DifyConfig(_env_file=example_env_file).model_dump())  # pyright: ignore
    config = flask_app.config

    assert config["CONSOLE_API_URL"] == "https://example.com"
    assert config["FILES_URL"] == "https://example.com"
    assert config["CONSOLE_WEB_URL"] == "https://example.com"

Ensure that your .env file is correctly formatted and located in the expected directory. Alternatively, set the environment variables directly in the docker-compose.yaml file under the environment section for the relevant service:

services:
  api:
    environment:
      CONSOLE_API_URL: 'https://example.com'
      CONSOLE_WEB_URL: 'https://example.com'
      FILES_URL: 'https://example.com'

If the URL is returning an empty string, verify that the .env file or the docker-compose.yaml file is correctly set up and that the DifyConfig is properly loading it [1].

I used the file upload following official document, the url property in deed showed. But I cannot use the variable in the following node. It's because when following node tried to get the url property, it's none.

@dosubot[bot] commented on GitHub (Mar 19, 2025):

To resolve the issue of the URL property showing as none in the following node of your workflow, you should use file.remote_url instead of file.url. This change will ensure that the workflow can properly access and use the file URLs, especially when the files are stored in an Object Storage Service (OSS) [1][2].

Yes this is an expected behavior, you can only get the url of the upload from the remote.
