Hello @dailyer! I'm here to assist you with any bugs, questions, or contributions you may have. Let's work together to resolve your issue!

I found a similar unsolved discussion titled "can not upload file in chat window" which might be related to your issue [1].

In Dify version 0.15.3, there are known issues related to file uploads, including errors like UnsupportedFileTypeError which occurs when the uploaded file type is not allowed [2]. Although Markdown files are supported as part of the document file types that can be uploaded, there might be specific configuration or validation issues in the published version that are causing this problem [3].

Ensure that the "File Upload" feature is correctly configured in the published version, and check if there are any specific error messages or logs generated when the upload fails. This might provide more insight into the issue.

To continue talking to Dosu, mention @dosu.
