[BUG] rich crashes ipython when printing a traceback after due to `StopIteration` error #2821

scottstanie · 2023-02-20T00:56:35Z

I've checked docs and closed issues for possible solutions.
I can't find my issue in the FAQ.

Describe the bug

Using %load_ext rich in python, printing a traceback will sometimes cause ipython to crash with an error RuntimeError: generator raised StopIteration

It's possible this is related to #2781, and maybe others with strange crashes/hanging?

Example code
(sorry i couldn't find one without pydantic, this was just the quickest/smallest thing related to what I was really doing)

saved into testrich.py

from pydantic import BaseModel


class Dummy(BaseModel):
    def __init__(self, **data):
        super().__init__(**data)
        self.new_attribute = "this should error due to pydantic"

then in ipython

I think this is the same underlying issue as #2800

opqpop · 2023-02-28T19:53:52Z

exact same thing is happening to me, what is the suggested fix for this?

this is breaking our prod build and we need an urgent fix, please let us know or we'll have to move off rich, thanks
