Hello @MapleLeaf-spec! I'm Dosu, your friendly bot here to help you with any bugs, questions, and contributions while you wait for a human maintainer. Let's dive into your issue together!

In Dify version 1.3.1, MD files should be supported for upload, as the supported document formats include Markdown (MD) files [1][2]. However, if you're encountering an error message stating "File type not supported" when uploading MD files on macOS 15, it might be due to a configuration issue or a bug specific to your setup.

The console errors you mentioned, such as the appName warning and the chunk-BAmLwY03.js TypeError, could potentially be related to this issue, as they indicate problems with dynamic resource loading and script execution. These errors might affect the file upload functionality indirectly.

To troubleshoot, consider the following steps:

  1. Verify that the file upload settings are correctly configured to support document uploads, including MD files.
  2. Check if there are any updates or patches available for Dify that address this issue.
  3. Investigate the console errors further to see if resolving them impacts the file upload functionality.

If the problem persists, it might be beneficial to look into any recent changes or updates in your environment that could affect file handling, such as browser updates or changes in macOS 15.

I can not reproduce this in our latest cloud environment.

biz.automator.trace and we do not enable this service for tracing purpose. This looks unfamiliar to me. Please check the configurations again and make sure you have setup the environment correctly.

Image Image However, I also encountered this issue in the latest cloud environment. I suspect it may be related to the macOS version. I'm currently using the latest version of macOS, and I did not experience this problem with the previous version. Could this be a compatibility issue with the latest macOS? I have tested across all major browsers and the issue persists.

@appleboy I am using 15.5 (24F74)
This issue has proven to be quite challenging, and I have not yet found any actionable leads. The problem occurs consistently across all major browsers I have tested

I think I found the key lines of this problem
where codes pop this message
and these are the difference between console debug on MacOS and Windows

which the r.type is 'text/x-markdown' on MacOS while empty on Windows (which may right by mistake)
