Unsupported upgrade request.

Hi,
I have recently upgraded my prodigy licence from the previous version 1.10(spaCy v2) to the latest version using spaCy v3. When launching my script for text categorisation I am receiving an error when loading the web interface which gives me:

What am I missing?

✨  Starting the web server at http://0.0.0.0:8051 ...
Open the app in your browser and start annotating!

Hi! I've never seen this one before but after some googling, it looks like this is related to uvicorn (the ASGI server library we use). See here:

question

```py app = FastAPI() @app.websocket("/ws") async def websoc(websocket: Web…Socket): await websocket.accept() await websocket.send_json({"msg": "Hello WebSocket"}) await websocket.close() ``` When attempting to run this (using UviCorn), it starts fine then, when i try and use my client to connect the the websocket, i get this error ```bash Python 3.8.6 (tags/v3.8.6:db45529, Sep 23 2020, 15:52:53) [MSC v.1927 64 bit (AMD64)] on win32 >>> runfile('C:/Users/Tobi/Documents/Scripting/Mixed/Webpage/main.py', wdir='C:/Users/Tobi/Documents/Scripting/Mixed/Webpage') INFO: Started server process [9580] INFO: Waiting for application startup. INFO: Application startup complete. INFO: Uvicorn running on http://192.168.1.88:80 (Press CTRL+C to quit) **WARNING: Unsupported upgrade request.** ``` This is my client code, its just supposed to be a very simple test ```py import websocket, time ws = websocket.create_connection("ws://192.168.1.88/ws") while True: ws.recv() time.sleep(2) ``` Let me know if you can help, or if anyone else has had similar issues with this.

According to this comment, it's resolved by uninstalling and re-installing uvicorn, so could you try that and see if it helps?
