there should be an actual traceback no?

LLogan M

Hard to say what the issue is without a traceback

RRehanOnText

no, there is not. that is why I am confuse as what is the issue?

LLogan M

Theres always a traceback. Just depends on where/how you are running your code

Factor out your code into a script that reproduce. Sounds like you are maybe running in a fastapi server?

RRehanOnText

yes i am using fastapi

LLogan M

Reproduce it outside of fastapi then maybe?

Did you try with traceback module as well?
