Hello @le0zh! I'm here to help you with any bugs, questions, or contributions you may have. Let's work together to solve the issue you're facing. If you need any assistance, feel free to ask.

I found a similar closed issue titled "[bug]upload file error" that might be relevant to your situation. This issue was resolved by a pull request that provided full support for opendal and synchronized configurations between .env and docker-compose ^[1].

For your specific case, in Dify version 0.15.2, ensure that when using the Workflow API's /workflows/run endpoint, you specify the file type as 'custom' for remote image uploads. This is part of the new "File Upload" feature, which supports various file types, including images. Here's how you should specify the file type:

{
  'inputs': {
    'doc': {
      'type': 'custom',
      'transfer_method': 'remote_url',
      'url': 'your-file-url'
    }
  }
}

Make sure the remote_url is a valid URL starting with "http" and is not None ^[2][3].
