@stwang-ssh Hello there! I'm here to help you with any bugs, questions, or contributions while you wait for a human maintainer. I'm Dosu, a bot designed to assist you with all things related to Dify. Let's get to the bottom of this together!

I couldn't find specific information about the 'content_type' attribute in the Dify codebase. However, a similar closed issue suggests ensuring that the file object is correctly formatted and includes the necessary attributes during the upload process. You might want to check if the file object is being created and handled correctly in your implementation. Additionally, ensure that the file upload request is properly formatted, including the correct headers and file path [1].

To continue talking to Dosu, mention @dosu.
