Hello @zhongty! I'm Dosu, a bot here to help you solve bugs, answer questions, and assist you in becoming a contributor. I'm here while you wait for a human maintainer. Let's tackle this issue together!

I found a similar unsolved discussion regarding a "File not found" issue while uploading a file to knowledge in the Dify repository [1].

For your specific issue, here are some potential areas to investigate:

  1. File Types and Sizes: Ensure that the files you are trying to upload are of supported types and within the size limits. The supported file types include txt, markdown, md, pdf, html, xlsx, docx, and csv [2].

  2. Configuration for Self-Hosted Instances: Verify that your FILES_URL is correctly configured in the docker/.env file. This should include the full URL with the IP address and port number if not using the default port 80 [3].

  3. File Paths and URLs: Check if there is a mismatch in file paths or URLs. Ensure that you are using file.remote_url instead of file.url to retrieve the correct image URL, and that the URL is accessed within the valid timeframe [4].

  4. Error Handling: Review any logs or error messages for additional context on why the 404 error is occurring. This might provide more insight into the specific conditions leading to the error.

These steps should help you troubleshoot the 404 error during file uploads. If the issue persists, consider reviewing the configuration and logs for any additional clues.
