Original Pull Request: https://github.com/langgenius/dify/pull/24411

State: closed
Merged: No

When migrating from flask_restful to flask_restx, the API interface has changed:

  1. flask_restful.Api has a built-in errors dictionary for custom error handling
  2. flask_restx.Api does not have this attribute and requires manual initialization

This is the previous error log

return self.ensure_sync(self.view_functions[rule.endpoint])(**view_args)  # type: ignore[no-any-return]
           ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
  File "/Users/liugddx/code/dify/api/.venv/lib/python3.12/site-packages/flask_restx/api.py", line 402, in wrapper
    resp = resource(*args, **kwargs)
           ^^^^^^^^^^^^^^^^^^^^^^^^^
  File "/Users/liugddx/code/dify/api/.venv/lib/python3.12/site-packages/flask/views.py", line 110, in view
    return current_app.ensure_sync(self.dispatch_request)(**kwargs)  # type: ignore[no-any-return
