I am deploying Omniverse DSX on an Azure VM running Ubuntu 24.04 with Python 3.10.20 and an NVIDIA Tesla T4 GPU (driver 595.58.03). The web UI loads, but streaming and agent features fail with the following error in the backend logs:
Any help is highly appreciated. Thanks
TypeError: _TypedDictMeta.__new__() got an unexpected keyword argument 'extra_items'
This error occurs when loading extensions such as omni.ai.langchain.agent.usd_code, omni.ai.chat_usd.bundle, and omni.ai.aiq.dsx. As a result, the backend does not fully initialize (the “RTX Ready” message is not printed), and the UI displays “Failed to load the stream. Failed to connect to Kit streaming. Make sure Kit is running with streaming enabled.”
