Self Checks

Dify version

0.10.0

Cloud or Self Hosted

Self Hosted (Docker)

Steps to reproduce

after you upload a file, no matter it is an image or document or anything other file, you can see a download icon on the thumbnail, it means we can download it, like this:

image

but when we download it, you will found it only 34kb, and is a html file indeed!

✔️ Expected Behavior

download the file we just uploaded, as normal thought.

❌ Actual Behavior

we download a html file, named after the file we just uploaded.

I found a couple of similar discussions that might be related to your issue:

  1. Where are the images and files generated by Dify stored? Also, the tool's API cannot access the generated files. - This discussion is still open and might provide insights into file storage and access issues [1].

  2. File URL as returned in dify workflow does not match the file location in s3 (self hosted instance) - This is another open discussion that deals with discrepancies in file URLs, which could be related to your download issue [2].

Regarding your specific issue, there are a few configurations in Dify's Docker setup that might affect file handling and download functionality. The FILES_URL environment variable is crucial for displaying the file preview or download URL. This URL is signed and has an expiration time, which could impact download functionality if not configured correctly. Additionally, the FILES_ACCESS_TIMEOUT specifies a time interval in seconds for the file to be accessed, with a default value of 300 seconds [3].

It might be worth checking these configurations to ensure they are set correctly in your environment.

@dosu hi bot, they're quite different issues OK?

The issue you're experiencing, where a file download results in an HTML file instead of the expected file type, could be due to several factors. Here are some potential causes and steps to troubleshoot:

  1. URL Configuration: Ensure that the FILES_URL environment variable is correctly set to an externally accessible address. This URL is used for file previews and downloads, and it must be properly configured to avoid issues [1].

  2. Signed URL Validity: Check the FILES_ACCESS_TIMEOUT setting, which determines how long a signed URL is valid. If the URL has expired, it might lead to incorrect file downloads [2].

  3. File Type Handling: Verify that the file type is correctly identified and handled by Dify. The system uses predefined lists of file extensions to differentiate between file types during the download process [3].

  4. Server Configuration: Ensure that your server is correctly configured to handle file requests. Misconfigurations in the server setup could lead to incorrect file responses.

  5. Check Logs: Review server logs for any errors or warnings that might indicate why the file is being served as HTML.

If these steps do not resolve the issue, further investigation into the specific server and application setup might be necessary.

Have you solved it yet? I also encountered the same problem in 0.10.1

Hi, @Copilotes. I'm Dosu, and I'm helping the Dify team manage their backlog and am marking this issue as stale.
