The above exception was the direct cause of the following exception:
Traceback (most recent call last):

The issue fundamentally arises from a discrepancy between the output of the LLM and our expectations.
We anticipated this:
Product Goals:
[
"Create ...",
"Provide ...",
"Implement ..."
]
However, the actual output was:
Product Goals:
- Create ...
- Provide ...
- Implement ...
This led to a failure in data validation. The error here occurs because even after retries, we didn't get the expected output.
Solution: We will enhance our data parsing logic to increase the success rate.
@qa6300525 Some fields can actually be ignored, because the post-role has no dependence on them, even if the parsing error does not affect the effect
https://github.com/geekan/MetaGPT/pull/41 almost fix this issue. pull & retry.
