When does this happen?

How others solved it

THEN Investigate underlying errors causing the 500 by examining vLLM's token generation and parsing logic. Note that temperature setting influences error frequency, suggesting a relationship between generated tokens and the error. Consider adding error propagation to surface the root cause instead of returning a 500.
