Self Checks

Dify version

0.3.34

Cloud or Self Hosted

Self Hosted (Docker)

Steps to reproduce

  File "/usr/local/lib/python3.10/site-packages/flask/app.py", line 1469, in dispatch_request
    return self.ensure_sync(self.view_functions[rule.endpoint])(**view_args)
  File "/usr/local/lib/python3.10/site-packages/flask_restful/__init__.py", line 467, in wrapper
    resp = resource(*args, **kwargs)

    return current_app.ensure_sync(self.dispatch_request)(**kwargs)
  File "/usr/local/lib/python3.10/site-packages/flask_restful/__init__.py", line 582, in dispatch_request

    return view(*args, **kwargs)
  File "/app/api/libs/login.py", line 94, in decorated_view
    return current_app.ensure_sync(func)(*args, **kwargs)
  File "/app/api/controllers/console/wraps.py", line 20, in decorated
    return view(*args, **kwargs)
  File "/app/api/controllers/console/datasets/datasets.py", line 269, in post
    response = indexing_runner.file_indexing_estimate(current_user.current_tenant_id, file_details,
  File "/app/api/core/indexing_runner.py", line 236, in file_indexing_estimate
    text_docs = FileExtractor.load(file_detail)
  File "/app/api/core/data_loader/file_extractor.py", line 37, in load
    return cls.load_from_file(file_path, return_text, upload_file, is_automatic)
  File "/app/api/core/data_loader/file_extractor.py", line 105, in load_from_file
    return delimiter.join([document.page_content for document in loader.load()]) if return_text else loader.load()
  File "/app/api/core/data_loader/loader/unstructured/unstructured_markdown.py", line 38, in load
    from unstructured.partition.md import partition_md
  File "/usr/local/lib/python3.10/site-packages/unstructured/partition/md.py", line 3, in <module>
    import markdown
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.
