Description

OutputFixingParser has been removed from the newer versions of LangChain, which breaks existing implementations that rely on it for correcting and validating structured outputs. We need to identify and implement an alternative approach that provides similar functionality for output parsing and correction.

Why This Is Needed

  • Current code depends on OutputFixingParser for ensuring output consistency.
  • LangChain has deprecated and removed this class in recent releases.
  • Without an alternative, workflows that require structured output validation and correction will fail.
