[hayescode]

Describe the bug
When uploading certain file types the mime types are not recognized.

Incorrect:

• Markdown .md
  • ERROR: defaults to application/octect-stream
• Python .py
  • ERROR: App crashes

  File "C:\Users\haze\CheersGPT\.venv\Lib\site-packages\engineio\base_server.py", line 229, in _get_socket
    raise KeyError('Session is disconnected')
KeyError: 'Session is disconnected'

Correct:

• .csv, .xlsx, docx, .pdf, .pptx

config.toml

[features.spontaneous_file_upload]
    enabled = true
    accept = ["*/*"]
    max_files = 20
    max_size_mb = 500

app.py

@cl.on_message
async def message(message_from_ui: cl.Message):
    for file in message_from_ui.elements:
        for key, value in file.to_dict().items():
            print(f"{key}: {value}")

mime: application/octet-stream

To Reproduce
Steps to reproduce the behavior:

Markdown:

1. Copy the README.md to your local computer.
2. Configure Chainlit with above settings.
3. Start app.py
4. Add local README.md to chat and ask "Summarize This"

Python:

1. Copy the user.py to your local computer
2. Configure Chainlit with above settings.
3. Start app.py
4. Add local user.py to chat and ask "Summarize This"

Expected behavior
Mime type is correct and app doesn't crash. Maybe if mime.guess returns the default application/octet-stream it can then infer based on the file extension in some cases?

Desktop (please complete the following information):

• OS: Windows 11
• Browser Microsoft Edge
• Version Chainlit 1.1.0rc1
