New version should invadiate basically all errors, try it now?

[e-p-armstrong]

In general what this meant was that the LLM made a mistake on a single step. That error was handled by default and the pipeline kept running. Should've been no problem at the time, even? Unless the model made the mistake EVERY time, which would be an LLM problem.

[StephenGenusa]

determination = decision_pattern.search(response).group(1).strip()

should be something like:

if determination_match := decision_pattern.search(response):
    determination = determination_match.group(1).strip()

I got this error many times, to avoid it i tried to change the llm i was using and its gone,

The problem was that the llm responses was not on the provided prompt format and does not contain the keyword algorithm looking for in the answer so it can make a decision.
