Error: Exception in ASGI application

[Woisek]

When I use promptgen to henerate some prompt using it the first time, sometimes I get the following error:

Running on local URL: http://127.0.0.1:7860

To create a public link, set share=True in launch().
Exception in callback H11Protocol.timeout_keep_alive_handler()

KeyError: <class 'h11._events.ConnectionClosed'>

During handling of the above exception, another exception occurred:

Any ideas?
