Troubleshooting Dust API: Image Upload Error Resolution Guide

Hi everyone, I try to use dust API to talk with an agent. I'm trying to provide an image to the agent using the image url (section contentFragments) but I can't do it. I always get the same error : { "error": { "type": "internal_server_error", "message": "Unhandled internal server error: Error: Error creating file for content fragment: Failed to process the file : Error: Failed resizing image. Input buffer contains unsupported image format" } } Could you please help me
