ModuleNotFoundError: No module named 'markdown'

✔️ Expected Behavior

I looked at the "change log 0.3.34" and opened and linked "Unstructured" correctly, but the error occurred.

❌ Actual Behavior

I added a markdown file to "create knowledge", but there is an issue that the module cannot be imported from the API server. The image I used is langgenius/dify-api:0.3.34

I have clone the project again and cleanup the data. And use a fresh new copy to start the application by docker. Looks good to me.
