请求大模型返回数据 self._fastapi_stream2generator 报错

まず examples/webui/dialogue.py の dialogue_page と、次にページのディスパッチ周辺にある examples/webui.py を読み、報告されたリクエストを再現します。examples/webui/utils.py:_fastapi_stream2generator を通じてモデルリクエストを追跡し、ログに記録された接続失敗を確認するとともに、報告された Streamlit 例外も確認します。ダイアログリクエストが報告されたどちらのエラーも発生せずに完了すれば完了です。
