❓ Question

I'm building an app and wrap the function pne.chat into a Restful API.
In my python termianl, I could import promptulate and run the pne.chat code, without any error.
However, when I start the Restful App in Flask, it reports the following error.

During handling of the above exception, another exception occurred:

RecursionError: maximum recursion depth exceeded while calling a Python object

My Python version:

python==3.9.0
promptulate==1.18.4
flask==3.0.3

Is this a bug?
