NotImplementedError: QAsyncioEventLoop.getaddrinfo() is not implemented yet

[batton]

I was pointed to the QtAsyncio module to allow me to integrate asynchronous calls into my PyQt app.
I have a langgraph app that was working stand-alone, but when I port the code into an async method of my PyQt app, I get the error mentioned in the title.

The offending code is this:

messages = await app.ainvoke(inputs)

ainvoke()

Is a standard langchain asynchronous function, and it worked when I ran the code in its own program before porting it to my PyQt app.

Can anybody please shed some light on this?
